I'm not totally convinced its really necessary on any board to denote what gender you are, I tend to AVOID this option in profiles. Through conversation, and your general interactions with people, many people can tell - or have a good guess if they are talking to a Woman or man. I think actually using the profile option is similar to wearing it like a badge, and its not even necessary for you to wear that badge on a forum to denote who you are, because you have nothing to prove to anyone. It just seems like labels to me and putting peoples identities in "boxes". Each to their own I suppose, if you like having "M" or "F" or which ever else in your profile though, I just think its NOT really necessary. 🙂
