The current wiki.musicbrainz.org is known as MusicBrainz Wiki but is actually about all MetaBrainz projects and even related projects. For example, it's used for MetaBrainz weekly meeting, yearly summit, and GSoC. This is because everything was under the name MusicBrainz before MetaBrainz branding became more prominent.

The long term is to make it fully MetaBrainz Wiki.

• The logo has already been updated to match MetaBrainz branding.
• MusicBrainz Server already supports changing the wiki domain name.
• However MusicBrainz specific stuff still has to be moved under the "MusicBrainz:" wiki namespace (OTHER-414).

Only then the wiki can be moved under wiki.metabrainz.org (with redirection).
