Since 2nd grade, I've heard Luke Skywalker... a couple years later it was Luke Duke (from the Dukes of Hazard) and intermittently from people with impeccable taste in films I've been called "Cool Hand".
And as you just showed us Andy, if anyone wishes to make it really easy - just go up to the drop down menu of Forum Actions, choose Edit Profile....and look down at the last entry option, I believe, and you can type in your "real" name.
No secrets here, mine is a very Dutch name and I could not really think up anything different actually, there are enough logins and passwords to remember in our digital age, so I thought I would just stick to my real name and hope I could at least remember that one...:)
