Rp Tutorials

So, when I go hunting for games or to see what's out there, I generally only hit up a few places. I am wanting to broaden my search and was hoping all you lovely people will help me as well as help others.

What RPG comm sites are out there that are either popular/active? What sites are great for posting a wanted line for a character you have in a game? I don't really do PSL's but I'm know a lot of us writers do like those, so what are the most awesome PSL sites?

Thank you all in advance for those who help me, as well as helping others out there, out!

P.S. I don't know what to tag this with, but if you'll let me know I'll do so!!
