. . . you may want to check out Josh Flanagan's post announcing his new free control “that allows users to view and edit their profile information” -- check it out here. It's inspired by the Whidbey Personalization Services and a TechEd presentation on the topic; I'm going to check it out.
Despite the new control, I don't know that I'll forgive Josh for dragging me onto the SeaWorld Wild Arctic Ride at TechEd -- I haven't been quite right since that simulation ride let me off.
