I'm looking through the cast list of the WoM project, in fact I'm this very moment writing a scene commenting on how many of the candidates reduced their involvement in AG to zero or just about that after they exited the tournament. A number of the veteran finalists ended up in the Counting Time Xatchat which, as Xzeno tells me, has had a few departures, but every now and then some of the other forum veterans (not necessarily involved in CT, like Kingryan and Thoad) will pop up here (on that note is Crimsonblade still around?). Then there's other users I think have gone, like Parsat, but then I got a request from him to update the poetry contest not too long ago too. And even if I didn't know he was still on AG I'd know he was still kicking it because every submission I make on DA seems to make him nauseated eventually lol (in all fairness he's asking for it).
Ultimately the only ones I have confidence in declaring are the admins and mods from the early generation, like DragonMistress (whom I still have tabs on), and Flipski and Calm (whom I don't).
