Greetings, Trence. There are quite a few games going on, and perhaps a few that you can join. The GM's frequent this forum, so you are sure to be noticed. In order to catch their eye, insert a character concept or two that you enjoy role-playing. Check out Kontact's
The Big Black Book o' Runners for what GM's would be looking for. Also, replying to that thread may lead your character to a job.
FastJack and Kot have put together some
sexy character sheet code that helps your future GM easily read your character sheet. If you feel like you have a good character concept, but are not sure your character is taking advantage of the 4th edition rules, post your character sheet in
Character Creation and Critique, and I am sure a fellow player will give you helpful advice.
My experience so far has been that there are not too many restrictions on awakened characters or technomancers, so don't feel like a rare character type will have a hard time finding a game. Most GM's I've seen frown upon free spirit characters, AI characters, or crazy metavariants, but if you come up with a cool backstory, I'm sure a GM will be compelled to invite you to play their game.
Most GM's here use the
Invisible Castle for dice rolls.
In this message, FastJack has given some pretty detailed information on how to use invisible castle.
Hope that helps!
