If you've been paying attention to Community Central, you'll know that there are changes regarding user groups (aka staff rights) that will activate today. Here is what I got from that blog post:
Forum moderator
- Forum moderator (default is Moderator) is now Discussions Moderator.
- Forum mods now have chat mod rights and can delete, move and edit comments on articles and delete comments on blogs.
Content Moderator
- A new staff position
- They automatically have rollback rights.
- They can delete, undelete, protect and unprotect pages, move and reupload files, and make redirects not be automatically created when moving pages.
As an on-topic question, how will this change things on the wiki?
