I have three names I usually go by

Furrylove - Originally it came from my druid on a WoW server. I always loved animals and well it could turn into a furry kitty so I called it Furrylove, although most people see it as though I like to hump animals, yes Nerevar you are not the only one.

Krutuz - And undead rogue I had originally called Kurtcobane (yes I know it is spelt wrong, the original was taken) after a few months blizzard changed it to Krutuz, and I have not seen one other person with that name plus it is kinda cool sounding

Drasnia - The name of a country from a series of books by david eddings, at first it seemed wierd to use a name of a country, but after playing my bloddelf mage for a while I got used to it and started using it!
