Commons should have a C or COM prefix redirecting to Commons, equivalent to the Wikipedia prefix WP. For instance:
http://en.wikipedia.org/wiki/WP:Image_copyright_tags goes to:
http://en.wikipedia.org/wiki/Wikipedia:Image_copyright_tags
http://commons.wikimedia.org/wiki/COM:Copyright_tags or
http://commons.wikimedia.org/wiki/C:Copyright_tags should go to:
http://commons.wikimedia.org/wiki/Commons:Copyright_tags
Version: unspecified
Severity: enhancement
Those usages (noted at bug 4676) are minor, and I think it would be reasonable to delete them all. Regardless, though, uses on en wiki are no obstacle to using the C shortcut on Commons.
Perhaps then we could come up with a productive solution, instead of de facto allowing COM, while in theory rejecting it.
I recommend we switch to CM, which does not appear to be reserved for anything, judging by http://www.silinternational.org/iso639-3/codes.asp?order=639_2&letter=c.

WONTFIX -> LATER
Well, that would have to be discussed with the local community. :-) (Considering CM is not used like C:/COM: are, you would have to see if the community wants it.)
(In reply to comment #2)
Apparently it's not going to be c:, see bug 4676.
If [[Special:PrefixIndex/C:]] is the only reason not to use "C:" as the prefix, it doesn't seem to be a very good one. I see two legitimate articles (one band and one video game) and a bunch of redirects, most of which point to categories and should be fixed to use the conventional prefix for category shortcuts on enwiki, "CAT:", instead.
Moving old LATER bugs to appropriate resolutions. This issue is old and no longer relevant today. COM: is used across Commons as a namesacpe prefix shortcut.
