now we have an official Ubuntux channel. It's #ubuntux.org at Freenode (servername: irc.freenode.net). Everyone who wants to get involved may join.
For the beginning we need graphical artists (for banners etc.), bloggers (writing about their experiences, news, tips'n'tricks, etc.), forum posters (howtos, everything what Ubuntu beginners could want to know). See you @ IRC :)
