My name is Ryley, and I'm a bit confused about the postings/where to start a game/how to even describe a game. I've read the FAQ's, but I'm still just a bit unsure.

Once you're ready to start searching for games: Check out: Wanted - Players and Wanted - GMs in the threads listings.

Unlike some other sites of this type (if you're familiar with them) - you do not make a character before considering the game you want to join (fairly common for some sites).  Here, you introduce yourself to a game/group/GM and join - and then make a character (though, many will still want SOME amount of information to get started.)
