Jonathan is my first name, and vt is constructed from my last name to distinguish myself from all the other Jonathans while not making myself too traceable. jonathanvt would look more consistent, but with forced capitalization that's not possible.
I have appeared as 62.194.128.65 and 62.194.128.232 before. As of now (03:37, 28 October 2006 (UTC)) nobody else appears to have edited Wikipedia with them.
