Typically, if your race is something else, we prefer it to be stated in your profile. And from there, what you do and do not do with your race is the call of the admins. If you as a player think that something fishy is going on in your scene with Joe Werewolf, you would PM an admin, and they would investigate, putting that scene on hold until it has been properly sussed out. However, there does not need to be an index of such things, simply because, this is stuff you need not know about other's characters. Just like people don't need to know everything that's special and cool about your dude. Just us admins. NPCs may even be of different races, and unless you have cause to know about that race, (generally speaking, you won't) that's the sort of stuff you shouldn't know.  Mystery is part of the fun.
