You don't have to tell us of course, some people use their real name anyway and others are possibly in the profiles (but I'm too idle to check). I don't really like my user name, but have become known by it on a number of forums. When I have tried to change it, I've allowed others to talk me out of doing so. Anyway, my name is Martin, I prefer it to my user name and you can use it if you want.
What's yours and do you mind it being used?
