Well, if you've never roleplayed before, I recommend Free to Mid-Casual roleplays. If you're really keen and a good writer, try High-Casual to Low-Advanced. There is no "beginner" roleplay per se, you just have to find the one that's right for you.
EDIT: Also, totally forgot to mention, welcome to the guild! May you follow the light of the Bump and kill the heretical Reply Blob! (In all seriousness, I wish you a happy time here :D)
