It is kept up to date as current running Role-playing Games. Some Game Masters have a prologue or alternative way of handling new players. The safest way is to post your interest within the "Create Character" thread of the game and the GM of that game will tell you if he has room, etc. Off the top of my head we have a new GM that isn't listed there that I know is looking for players: Arthos's Pathfinder Campaign Character Creation.
Do not feel odd jumping in a game. IF you like Dungeons & Dragons you can jump into any one of mine and I can get you in the game. I think the path finder games you can do it too. I know one has not even started as people are still getting characters all rolled up.
