I'd like to believe most of us do this. Mine typically include Juppiter (or simply Jupp), Kickle, GobJunkBot, and Caitiff. Not surprisingly, my current name is available on most sites I set up with an account.
Just curious, what's the significance of the name "Creo" anyhow?

Nice. I can understand why 'Creo' is taken: there is a rapper called Cre'o, so this might spark some confusion.
