i noticed there is a gender option, i checked male, but can you make it visible when someone posts on his profile, and also as suggestion you could add a race or ethnicity field so we can know a bit about who we deal with and maybe a nationality or country option in the form of a flag or whatever. thank you.
What makes you think anonymous posters will be honest in saying what they are? There's little penalty for lying here.
Fairness dictates that gender identity be expanded to include:
Transgender
Bisexual
Male with breastesses
female with battery device
Male prone to self gratification
Bisexual is not a gender. The three you list below it are merely subsets within known genders.
I rather enjoy wondering and sometimes guessing the genders of various posters. Some I can tell by their screen name, some by their avatar, some by their posted comments. Having all poster's genders exposed would spoil my guessing game.
