So, how do I do this?

Alrighty, I have an idea for a RP that I'd like to start. Its set in a sci-fi setting, so basically do I just head on over to futuristic and post the first post full of info and then declare the RP open for business?

As for the actual game. Is it OK to want to approve characters? I write up that I did is really general. It described the setting and some basic races, abilities and skills, plot starters, etc. But that's about it since I don't want it to be to restricting. But I want to limit super godlike characters.

What about OKing certain abilities or something like that?

Any other tips for a freeforming newbie?

And yea, I'm going to jump into a few other games before I post mine. Just so I can get the hang of it. I'm so used to structured stuff with tons of rule and rulebooks.

As the GM of an RPG, you have complete creative control of it. You are only limited by yourself; obviously, if you make ridiculous rules or change them at whim to suit yourself, your RPG will likely die. On the other hand, if you're fair and make it a fun RP to play, it'll cruise along pretty well. We'll never force you to do anything but what you want to do with your RPG, and never limit you in that capacity.
