The Contact Us menu item in the MusicBrainz menu refers to the MetaBrainz.org contact page. The text under the IRC header only mentions #metabrainz, but that is the development channel. Shouldn’t the #musicbrainz channel get a mention there too? After all that is where user questions are supposed to go.
I see no reason not to – it is one of the two main channels, so we should add it!
I think this is for “historical” reasons. To begin with metabrainz.org was more separate from musicbrainz.org, so MusicBrainz’s “contact” page was still living at https://musicbrainz.org/doc/Contact_Us – which was made a redirect to https://metabrainz.org/contact in November 2015:
But yes, to changing it. I can put in a PR later.
Edit: Made a ticket:
