My registration for a new account went quite smooth. Confirmation email arrived in seconds. After the success, I revisited my profile to add some info, signature, invisible...etc. I also decided to "change" my gender to "(unspecified)." Instead of confirming this change, the system gave me an "unspecified error" message at the top of the screen. My first thought was the system's forcing people to "stick to" their genders. Same error message with my 2nd & 3rd try picking "(unspecified)" for gender change, so I gave up. However, I checked my profile moments later, my gender had successfully been "updated" to "(unspecified)." So I am not sure if the unspecified error message I saw was a system glitch. Just thought your IT guys may want to double check the behavior.
