Hiya Mandy!
I find it helpful when people put their name under their Avatar picture. Unless of course your name is part of your screen name! (um, like mine)
Quite a few people use avatars of Jake or Heath (which is great) but when the screen name doesn't yield a clue to the persons name or sex, then it starts getting confusing.
Know how when you see a litter of kittens or puppies and you want to know their sex? You pick them up and flip them over to look! That might get awkward to do in New York at the Brunch! He he he! Just kidding! From what I've seen so far from Avatars we have a good looking group, male and female.
