Welcome to the guild! You'll like it here, assuming you don't go hollow.

I've never really been all that great at telling people how to roleplay, but I would have to say communication is definitely important. Getting to know the people your roleplaying with goes a long way. I'm sure other people can come up with some better advice.

As for my favorite roleplay, it'd have to be the first one that I created. It was the generic post-apocalyptic setting, with half breed mutants. It was still a lot of fun though. The website we were posting on shutdown before we could finish it, which just sucked. A year worth of effort down the drain.
