well.. a clan should be a community, active in any way (ingame, forum, irc, events). A clan should have aims.. (diffrent to goals)
and.. thats what I think: it should not be the most important thing to become offical.. cause its shown in the subtext and gives a bad taste to all activities..
just wait untill you think you cant handle the clan without a own board and everybody ask you: "why you arent offical??"
this is the time to contact a clan-mod..
