WikiProject League of Copyeditors is a WikiProject that is dedicated to copy-editing articles on Wikipedia, or correcting grammatical, spelling, or stylistic errors within them. It was started on 22 November 2006 by Trusilver (talk · contribs), and originally had ten members. Currently, it has grown in popularity, and, having 228 active members and 71 inactive members, it is one of Wikipedia's largest maintenance projects.

The WikiProject has made a very good deal of progress in copy-editing, as evidenced by the time line on its main page, completing hundreds of articles, but as over 2,000 still remain, they will require a good deal of help to completely clear out the backlog.

• For articles that are featured article candidates or under featured article review where the only remaining reason for opposing is a need for copy-editing, requests can be added and handled at Wikipedia:WikiProject League of Copyeditors/proofreading#Requests for FAC and FAR articles.
• If an article is a good article candidate or under good article review, requests where the only remaining issue for which editors oppose is a need for copy-editing, requests are added and handled at Wikipedia:WikiProject League of Copyeditors/proofreading#Requests for GAC and GAR articles.
• For articles that do not meet the above criteria, requests can be added and handled at Wikipedia:WikiProject League of Copyeditors/proofreading#Requests for other articles.

If an editor consistently impresses with excellent copy-editing, the project has its own barnstar that you can award that user. Its syntax is {{subst:The Copyeditor's Barnstar|message ~~~~}}.

To help the project, you can add your name to its members list and join. Also, articles that need work can be found at Category:Wikipedia articles needing copy edit, Wikipedia:Pages needing attention, and Wikipedia:WikiProject League of Copyeditors/proofreading.
