One of the major points of a forum is the written rather than spoken style, and that the posts don't disappear just because you're not there when they're posted.
I certianly have nothing against this existing, but I don't feel it appropriate to deem it official. We don't even have an official IRC channel for the forum itself (albeit #neolemmix somewhat acting as an unofficial one).
EDIT: Over the time since this message was posted, it's become more official (and pretty much replaced IRC). However, I'll stress that as forum admin, I still reserve the right to later declare it "not official" if I feel it isn't being run in a way consistent with the forum's values. So far, I have no reason to believe this is going to happen, though - it's a "just in case" statement, nothing more.
