My name came from a kind-of pen pal I have from California. He called me "Prince Lex" once in a message in 2002 (my name is Alexander, people call me Alex, Lexi, Alexi, Alexis... sometimes my mother calls me Xander. People generally just have a field day screwing about with nicknames for me. Most people that speak colloquially in Glasgow call me Alec because Alex can sometimes sound too polite in certain accents.)
I don't like being called "Alec" or "Alexander". "Alexander" is OK if it's someone I'm close with. Most people just call me Alex.
Anyway, the name Prince Lex just stuck as my internet nickname after the message he sent me. It's my name everywhere. I played with "phoenixheaven" for a while but after I adopted Prince Lex I changed my name on every board to it. It's my name everywhere that I'm a member, I like it because its personal to me, it came from someone I care about and it's not that common at all. There have only been a handful of places I haven't been able to register it (like youtube for instance).
Thats really all there is to say about it!
