I have lots of pennames. Maybe not that many; it's up to you.
Camelia Oxcreod - not a pen name, something inspired from a movie, the root of my current hotmail email address.
Saturday Stace - I intend to use it as a pen name. One day. ;-_-
CuteBrownSquirrel - egash. I prefer plain Squirrel.
Stasya - of course, -bows-.
Anastazsia - the version people find harder to type out.
Zenetta (Catucci Torelli) - hmm...
Oh, and my latest one
Adelaida Zabinto - I have an affection for the letter Z.
mm.
