Keep an eye on this forum and you can sometimes find interesting games to join especially on the Role-Playing thread
You have to be patient because it takes a while for a "serious" game to get started ie get enough players together via the forum to start a 10 or 22 player game
Also check out the "Find Coplayers" forum
There is a thread "Players League 3" that is a bunch of serious players almost ready to start a game - this Friday is the target start date I think - it might be a big step up for a new player but I am always willing to give advice (may not be the best but I have had a few games under my belt)
