I really like putting Old English or German in my names, all of which I thought were pretty unique.

Quidamtyra: quidam - unknown; tyra - beginner
Quidessence: taking "Quid" from my main, playing with the word "quintessence" since she is my bank alt =p

It took me a good 2 hours of looking up old english words to come up with Quidamtyra. Now I couldn't change it if my life depended on it, I absolutely love the name!

I can't stand people who have names like Istabyouhaha, where's the innovation in that?
