Two more Wikipedians were granted CheckUser rights this week: Mackensen and UninvitedCompany. Both are former members of the Arbitration Committee; Mackensen was elected in the January elections and served until he resigned in February, while UninvitedCompany was a member of the initial Arbitration Committee who served until his resignation in February of 2004. This brings the total number of CheckUser status on the English Wikipedia to 14, including Essjay and Ambi, who were both granted access last week.

A noticeboard for reporting and enforcing decisions of the Arbitration Committee was proposed this week. Although similar to the existing page from ArbCom requesting administrators to implement Arbitration decisions, the new proposed noticeboard would be for users to report violations after the respective Arbitration case had already closed.

The English Wikinews' Arbitration Committee closed its first case this week. The case, which involved an administrator's deletion of userboxes, resulted in the Arbitration Committee ruling for the creation of a "userbox whitelist", which would include language and localization userboxes, as well as others approved by the community.

The Czech Wikipedia's Arbitration Committee closed its first complete case this week, against Rosta. Although it was actually the second case accepted by the Czech ArbCom, it was the first case to run through the entire Arbitration process.

Fifteen new Wikipedias have been created, in the following languages: Piedmontese, Dutch Low Saxon, West Flemish, Ligurian, Kalmyk, Tetum, Papiamentu, Romani, Samogitian, Ripuarian, Pennsylvania German, Franco-Provençal/Arpitan, Cantonese, Banyumasan, and Norman.
