I volunteer as DM tribute. I could do Saturdays every other week. My DM experience is a bit limited, but I've done a bit in person, a bit on roll20, and I've been playing as a PC on roll20 for about six months now. At the very least I'm past the stage where I have to consult the rulebook for everything ;) I've had a peek at the Tal'Dorei campaign guide and I really like the way it's been put together - seems really well balanced between making suggestions and letting you take the reins.
