Heya folks!
Howdy,
the "Players Wanted' thread will show you ads for GMs looking for players...as a GM you may bump your add every 7 days ( they have a timer).
you can check the games out and see how active they are. Some GMs have alot more time, and/or more dedicated to thier game. Others...as you say RL happens.
in the advent you see a game you like, you can go to that game, send the GM a RTJ or a PM and see how your Free time, fits in with the game?
Bottom line?..don't be afraid to ask.
