Salutations!
Heya Kpol and welcome to RPol, you'll find anything you want here and so many great games from freeform to about any system game you like.
A few tips for you are below:-
Make sure you turn on your rmail by going to the link at the top that is User preferences, there you will find some settings to play around with including the rmail one as that is how you and most GMs can talk.
On the main menu there are two forums you can find what you want to play in
Wanted: players
Wanted: GMs
At the bottom of the main menu you will also find search link to find games and other good stuff.
So all I can say now is
HAPPY GAMING!!
