Why would you choose your gender, but not have it show up on your profile page? I think that should be added.
You can always type it in yourself.
What is Gender good for anyway? It'd be nice if it were a variable that could be used in-game.
I think you mean by letting the player choose. If it was a variable that was set in the member profile, I guess it would cause issues for visitors. Oh well, nothing's perfect.
