Hey Zach!

Welcome to RPG. If you are looking for (only) tabletop RPG's styled roleplays, here's where you should look. [url=http://www.roleplayerguild.com/forums/39-tabletop-roleplay]Tabletop roleplay[/url]. I'm not an expert on tabletop (I'm not an expert at anything) but I'm sure you could find what you need there. 

Otherwise, you should probably look around the boards a bit, find something that suits you both in the subject matter as well as post length and such, and find something you might like. I can guarantee that most GM's don't care if you are new to the guild, since writing is something dictated by skill and motivation and not post counts. 

I wish you the best of luck and for any questions feel free to PM me (or any of the others that offered in this thread!)
