Your Name

Cake • It's called the American dream because you have to be asleep to believe it.
I see people change their names for The Craft - sometimes legally, sometimes it's only used when working with magick. 
Right before my initiation ritual, my teacher asked me if I wanted to go by another name for craft workings (and said that if I didn't have one that I could get one at any time if I wanted). I decided to just stick to my birth name, and at this point I can't see myself going by another name. 
But I was wondering who all here chose another name - why did you want the name you chose? What meaning does it have to you?
