Nice to meet you, Kabe!  Don't be shy about asking questions - the people here are friendly and you're sure to get an answer before long.
Here's a few links just to get you started, and I'll send some more along shortly.  Be sure to frequent this forum, because there's a LOT that happens here, and I have no doubt you'll enjoy yourself.   

The 
General section and the 
Real Life section are good places to start off - there's all kinds of discussions going on all the time, serious or just silly.  
If you're interested in RP, our 
Role Play area is very active, and there's a lot of variety.
And the 
Games section is a fun place to pass the time and get that post count up.
