I just guess what gender people are I didnt even know you could look them up. I do assume all the posters in the ladies forum are female....
Sometimes i do get things wrong, even in real life when the person is right in front of me, but thats only if I meet them the first time. I quickly apologise if Im wrong. I dont insist like some people do that just cos your hair is short that you are male or if its long you are female.
