After the recent launches of Wikiversity and Wikiversity Beta, a search for a logo for the new projects continued. There are, as of press time, 11 proposed logos to replace the current temporary version, a mortarboard, which cannot be used because of licensing restrictions. In addition, discussions for a motto and mission statement also continued this week.

This week, a flurry of editing resulted after the International Astronomical Union voted to change the definition of a planet to exclude Pluto, an item that was still near the top of "In the news" as of press time. Several articles were immediately updated, such as the articles "Pluto", "planet", and "2006 redefinition of planet". Ironically, though, the featured article on the day of the change was the planet Mercury, which became the smallest planet by size after Pluto's "demotion" to a dwarf planet. The featured article was updated a few hours after the change in Pluto's status.

Though the Encyclopædia Britannica updated its article on Pluto shortly after the change, many pointed out that its other relevant articles were not rectified, such as the one on Mercury in the Concise editon, which as of press time still called it the "second-smallest major planet (after Pluto)". The Concise Edition article about Pluto still refers to it as a planet.

As a result of the case, 8bitJake, Bazzajf and the IP address 62.77.181.16 were placed on probation and banned from editing articles relating to Washington State political figures.

• Dionyseus: Closed on Wednesday after a two month hearing, a case involving Dionyseus and Danny Pi, and their actions on Veselin Topalov, an article on a Bulgarian chess player accused of cheating. As a result of the case, Danielpi was banned for one week for "discourtesy and personal attacks", and Dionyseus was advised to "consider carefully the suggestions of others regarding punctuation and other matters he is not familiar with."

• Marudubshinki: A case involving the actions of Marudubshinki. Snottygobble, I@n and others allege that Marudubshinki has operated an unauthorised bot, and misused his sysop powers by unblocking himself and allowing his bot to delete pages. Marudubshinki has not presented a statement in his defence.

• MONGO: A case involving the actions of MONGO, rootology, and others. The case centers around Encyclopædia damatica, and an article posted on the site portraying MONGO in a negative light.

• Ed Poor 2: A case involving Ed Poor. JoshuaZ and Consumed Crustacean have accused Poor of POV pushing and disruption; Poor has not introduced evidence in the case. Ed Poor was party to two prior cases; the first was closed after Poor resigned his status as a bureaucrat, and the second resulted in his desysopping.

• Pat8722: A case involving the actions of Pat8722. BorgHunter has accused Pat8722 of edit-warring. Pat8722 has requested that the ArbCom stay the case while he pursues 6 pro se cases in the American courts, and has agreed not to edit Wikipedia in the interim, but has not yet filed a formal motion to stay the case.

• St Christopher: A case involving St Christopher Iba Mar Diop College of Medicine, a school whose accreditation status is in dispute, and in particular the behaviour of ParalelUni on the page. Dmcdevit has proposed remedies affirming the community ban of ParalelUni, and banning all single-purpose accounts from editing the article. However, no other arbitrators have yet commented on the proposals.

• Kehrli: A case involving the actions of Nick Y and Kherli on Mass-to-charge ratio and related articles. Both protagonists accuse each other of POV pushing, adding unsourced information, and adding dispute tags without reason. Fred Bauder has proposed remedies banning Kehrli from articles relating to M/z, and from changing the notation m/z where found to any other notation. However, no other arbitrators have yet commented on the proposals.

• Israel-Lebanon: A case involving the actions of AdamKesher, Tasc and others on 2006 Israel-Lebanon conflict. AdamKesher accuses Tasc of removing relevant external links which satisfy WP:EL, and he denies the allegation. In response, Denis Diderot accuses Kesher of "using Wikipedia as a tool to promote his POV". Fred Bauder has proposed remedies permitting the linking to blogs which offer contemporary comment on a current event from Wikipedia pages, cautioning all editors to use common sense above literal interpretation of Wikipedia policy, and permitting any editor "particularly Tasc", to be banned from the article for an "appropriate period" should they engage in edit warring on the issue. These proposals have yet to be commented on.

• Deir Yassin massacre: A case involving the actions of KimvdLinde and Guy Montag on Deir Yassin massacre. KimvdLinde alleges that Montag has violated his probation by rewriting the article, unilaterally moving it to "Battle of Deir Yassin", violating copyright and votestacking. In return, Montag refuses "to participate in any of these proceedings", and alleges that KimvdLinde has abused her admin tools by exercising them in a dispute in which she is involved. Fred Bauder has proposed remedies banning Montag from articles relating to the Israeli-Palestinian conflict, and suggested that Montag's probation be extended. However, no other arbitrators have yet commented on these proposals.

• Warren Kinsella: A case involving the actions of Arthur Ellis, Pete Peters and others on the Warren Kinsella article. Both users accuse the other of disruptive edits on the page, and Peters and others acccuse Ellis of sockpuppetry using anon accounts, while Ellis alleges that administrators dealt inequitably with him and Peters. Fred Bauder has proposed remedies banning Ellis indefinitely from all articles relating to "Canadian politics and its blogosphere", and limiting him to one account. No arbitrators have yet voted on these proposals.

• Zer0faults: A case involving the actions of Zer0faults and Nescio on Template:War on Terrorism, War on Terror and related arguments. Nescio alleges that Zer0faults has engaged in violation of WP:POINT, disruptive editing, and "uncivil remarks". In return, Zer0faults alleges that Nescio has failed to assume good faith, violated WP:POINT and WP:RS, and failed to provide explanations for his reverts. A single remedy that would place Zer0faults on probation was suggested by Fred Bauder, but has not yet been voted on by other arbitrators.

• Intangible: A case involving the actions of Intangible. Cberlet alleges that Intangible has used an "aggressive and confrontational" editing style to push his POV (partly through the wholesale deletion of the term "far right" from numerous pages), making sweeping edits and reverts with little or no discussion, and being "contentious and confrontational" in talk page discussions. Intangible vigorously denies the allegations. A remedy, supported by Fred Bauder, Sam Korn and Dmcdevit, would place Intangible on probation. Other remedies, proposed by Dmcdevit, and not yet voted on by other arbitrators, would also place Tazmaniacs and AaronS on probation.

• CoolKatt number 99999: A case involving the actions of CoolKatt number 99999 on WWOR-TV and related articles, as well as the actions of Crossmr, Kramden4700 and others. A temporary injunction has been enacted, which bans CoolKatt from editing pages other than his own user pages and the arbitration pages for the duration of the case. Remedies banning CoolKatt from U.S. television articles for one year, placing him on probation, and ordering the deletion of all user subpages that violate userpage policies have the support of Bauder and Korn.

• Ericsaindon2: A case involving the actions of Ericsaindon2, Coolcaesar and Will Beback. Coolcaesar claims that Ericsaindon2 has tried to insert original research, has disrupted Wikipedia, used sockpuppets, uploaded images violating copyright law, and failed to assume good faith. In response, Ericsaindon2 claims that Coolcaesar has contributed equally to the dispute, and that Will Beback has misused admin powers, in particular with incorrect and biased application of the 3RR. Remedies have been proposed limiting Ericsaindon to one account, placing him on probation, and banning him for one year, and have the support of five arbitrators.

• Heqong: A case (formerly referred to as Chiang Kai-shek) involving the actions of Heqong (formerly Chiang Kai-shek) on China and Taiwan-related articles. Proposed remedies placing Heqong on personal attack parole and probation, and banning him for one month for personal attacks have the support of three arbitrators.

• His excellency: A case involving the actions of His excellency. The case involves the actions of His excellency on Islam-related talk pages. Remedies banning His excellency for at least four months, placing him on personal attack parole, and placing His excellency and Timothy Usher on probation have attracted the support of five arbitrators, as has one permitting the use of "traditional Muslim usages" such as "Salam, brother" on talk pages, so long as they do not create a hostile atmosphere for non-Muslims. Consensus has not yet been reached on other proposed remedies.

• Sathya Sai Baba: A case involving Andries and SSS108's actions on the article Sathya Sai Baba. Both have accused each other of "POV pushing", and violating Wikipedia's policy on original research. Proposed remedies that unsourced or poorly sourced information be removed from these articles, and a complete amnesty for Andries and SSS108 for any unreliable information they may have added in the past have the support of four arbitrators.

• Israeli apartheid: A case involving the actions of editors and administrators on Allegations of Israeli apartheid (formerly at Israeli apartheid). The article was the site of a move war during a poll to determine the article's naming. Remedies encouraging negotiation and mediation, admonishing administrators involved in the dispute, directing discussion of issues to Wikipedia:Central discussions/Apartheid, and granting an amnesty to all users except Zeq have the support of six arbitrators.

• Eternal Equinox: A case involving Eternal Equinox. Several users complained that Eternal Equinox has been trying to claim ownership of articles with edit wars and abuse directed at those who try to edit them. Eternal Equinox claimed to have left Wikipedia, but the other parties argued that this was not credible because of a number of similar statements made previously. Eternal Equinox has since returned, editing anonymously from several related IP addresses while acknowledging his or her identity. If closed, Eternal Equinox would be placed on probation and personal attack parole, and Jim62sch would be cautioned to "avoid teasing or taunting sensitive users".

• Añoranza: A case involving Añoranza. Users asserted that Añoranza had been incivil, and had filed a retaliatory request for comment and request for checkuser. The dispute involves the usage of terms such as "Operation Iraqi Liberation" for the 2003 invasion of Iraq. If closed, Añoranza would be banned for one week for the disruptive way in which he went about bringing the terms to light and the parties would be encouraged to enter into good-faith negotiations into the matter.
