Hi! I actually just signed up to say that I would love to play in this kind of game; I haven't done play-by-chat since the WW Moderated Chats went down.
I'm familiar with all the gamelines, but I don't pay much attention to Vampire or Werewolf: I read and play Mage and the yearly limited lines. I'd be happy to help out with setting design and backstory/NPC work on those parts, but I don't think I can commit to STing duties on a regular basis at this point, as most of my free time is going towards work on the WoDCodex.
