Hi Donny! Which Role-playing Game system are you interested in playing so I can point you in the right direction?
I have played a lot of 3.5, 4.0, Savage Worlds, and Pathfinder. My last group dabbled in everything from Vampire, to Gurps, to Call of Cthulu to LotR...I haven't done any Play By Post since I did some E-Wrestling back in the late 90's (Laugh)
No worries, the format is easy to get used to. Just spend a little time looking around so you get acclimatized.
To create a character for those use these:
* Dungeons & Dragons 3.5 Create Characters For Play By Post
* ICon's Kingmaker AP Pathfinder Create Characters
At the top of this board: Board, Card, & RPG Reviews there are some topics that are 'stickied' that can help you with the 1-2-3 steps but if you are unsure please ask here and I will point you in other directions.
Both those "Create Character" Links I gave you are looking for players and I'm sure the Pathfinder one will be glad to have you.
