See, this is the type of thing I should have done 6 weeks before moving to Corvallis, not 6 weeks after. 20/20 hindsight, I suppose...
ANYWAY! Yeah, I GM'ed in Portland since 4th came out, and played (or ran) a few other games, too -- mostly assorted "white wolf," but some d&d / d20, too. The group I played with in PDX was almost entirely GMs, so we'd "round-robin" the games: one person would GM the game one week, then next week someone else would run the game. It worked surprisingly well, and completely removed the threat of dreaded "GM burn-out." Of course, if someone wanted to run a few games in a row, we'd always go with that.
But that's neither here nor there. I'm in Corvallis, I have the 4th ed books, and I'm looking for some players to try the game out. If you're a part-time GM too, then you're perfect; if you're only comfortable as a player, you're still super-fly.
Cheers.
