The first game that F-T modded we did new screen names for everyone. They were secret names like codes ... Fox and Ravens and White Flame of Tar Valon are actually hold overs from that game, they liked them so much they kept them.

Anyway it didn't work out that well because everyone has such distinctive posting and writing styles that it turned out not to be such a secret and we all figured out who everyone was within a couple of days (real time days, not fake days) of starting the game.

So I would be game for trying it again, but I don't know how effective it will be. And that's my two cents on that.
