Welcome, Gei! You joined on the best day, April Fools Day!
I warn you. Things get pretty nuts around here on April 1st...ssh. I wasn't supposed to tell you this.
The main thing on PPT is to post and make friends. Before you know it...you'll have all sorts of friend here.
Just try not to post too much. They're charging NP to post now*.

Pshaw, though. I highly doubt it.
