I could possibly run something as a solo game for you. My personal preference would be to use the Heroes against Darkness system, which is a freebie D&D clone that is pretty simple to use. Rules can be downloaded (free and legal) at

I have a game already set up with my own sandbox world. It is gradually getting fleshed out as we play. I have a group of PCs but could run you separately to them. Maybe you could meet up in game, or maybe not...

I would use the same game to save duplicating information but could just run you on a different group thread so you wouldn't need to interact with the others.
This should give you an opportunity to get use to the style of play here on RPOL, and as a solo game you can go at a pace that suits you.
