eb was my first login name. It's been my initials since I was 9, and it's a name I associate with myself. Never dreamed it would become so famous.
sleeky came about when I inadvertently used someone else's alias in the old "cathouse" forum. I asked for suggestions for a new alias; sleeky was the best one and it's the only one of my old nicknames that stuck. Except I still use "Eilonwy" (from the Prydain books) when I play games.
I'm 14 years older and considerably fatter, but I think I'm still pretty sleek.
