You've just got to jump in, how else can we get to know you if you don't join in?
We're friendly here, for the most part.
I tend to avoid what I call "the big 3" because they tend to get ugly.
1. Politics
2. Religion
3. Sexuality
But that's my own personal rule for myself.
I'd suggest The main forums, the word games forum, and the MLP forum for ya.
There's also an irc chat option if you want something more fast paced.
