Re: Hi! New to PbP.
Well, if you want to get away from the Tolkien inspired stuff may I recommend the following: Exalted, GURPS, in particular their version of 'Bunnies and Burrows', (Fore Mentioned) Lady Blackbird, The Window, or Monsters and Other Childish Things. Of those the only one I have not personally played is the last but my friends all recommend it highly.
There are a multitude of systems and genres available on this site and you will soon find yourself embroiled in more games than you have time to play if you try to take in even 1/1000th of all that is on offer here, so pace yourself, and as sithraider said, read the FAQs and the rules threads of each forum: read them until you have them memorized, it will help you a great deal.
