I have noticed that there is no way to tell if a person is male or female on here. I think maybe there should be an area that tells you their gender.
I also think on the profile part there should be an area where you can say whatever you want about yourself so people can get a better idea of who you are. Like, a place to say your name and things about yourself other then what your into, or post a picture of yourself. Something of the sort.
I really hope my suggestions are taken into consideration.
