Gen07: Okay, is that all, or is there any extra info I need to know!
Keep talking in the forums, be an active-ish part of things, and you will soon be qualified for this.
I can recommend some of the forum games to get yourself hooked on the forums here. Over time you will transition from the games to look at other posts and discussions and might find yourself taking part in those as well. :D
If you are interested in games of social deduction, I recommend to you
Forum Mafia. Ignore most everything between the first post and the most recent posts, the rest is largely banter between players, only out-of-game. This thread includes the links to the sign-up threads for various games as well as links to the various games themselves.
Two more fun forum games are
Just Three Words (where you go to the last post and write three words which might or might not apply to the previous post) and
Word Association Game (where you go to the last post and write a single word which you associate with the previously-used word).
