Following on from the avatar threads, it might be interesting to find out why people chose their usernames.
Mine came from the "Prelude to Dune" novels, by Brian Herbert/Kevin J. Anderson.
We know Chewie chose his because he is excessively hairy :earl:
I'm pretty sure MagicNakor got his from Raymond E. Feist's "Riftwar" saga.
Does a person's username affect your perception of them?
