Gary--
Thanks for your reply. Certainly, in the newest incarnation of the D&D game, Tharizduun is playing a major role; from Return to the Temple of Elemental Evil to the Living Greyhawk campaign, we're seeing T's cultists all over.
As for getting in touch with Mr. Lakofka, I'm having trouble even finding out if he has a presence on the net. I know he wrote two articles for Canonfire and the Oerth Journal, but that was a few years back. I understand he's also a major figure in the Diplomacy world, but again, I can't find anything recent from him.
