"Jessica" is pretty popular too but when someone talks to me on the forums they spell it with a 'k' (hence my user name! ) and I did it that way on purpose.

Most of the time though when I refer to someone on forums I refer to them by their username to avoid this problem unless they prefer to be called by their real name (I've had some people get mad before because I would refer to them by their usernames and not by their real name.. )
