He led the work on Ruins of the Lost Realm for 2e.Sounds good, GH did some work on TOR1?
Either way, he's had a hand in some pretty good stuff.
Nice to see another release for this (since I've just started a pbp game.)
He wrote the excellently (and excellently reviewed) Darkening of Mirkwood 1e campaign, alongside Heart of the Wild and Tales from Wilderland (Francesco Nepitello and a bunch of other folk get prominent credits on some of these too for additional writing). Gets the feel and tone of Middle Earth right.
In particular, he's written a lot of adventure path/campaign stuff that has been critically acclaimed, albeit I only personally know his TOR work: The Dracula Dossier (Night's Black Agents), Eyes of the Stone Thief (13th Age), Pirates of Drinax (Traveller).
He's also a novelist, and I should check out his books one day as I like his RPG stuff.
Good luck on your play by post game! I'm playing in some and running one, where we're just finishing out first adventure. Play by post for me for the foreseeable as I've just had my second child.
