I've used a lot of psuedynoms and aliases since I first started using a modem back in the late 80s. Started with Smokey Topaz (which later got shortened to Topaz and then reversed to make Zapot)... I used dyce for a while... after that I became Blue Lady and then on muds I started using Twyla.
Eventually on telnet talkers I started using flutterbye and umopapisdn (which I tend to still use the most today).
I've also used e-mail addresses like fbye, amj, ajhenry, bleu, and joy (which is my rl middle name).
Its funny to think back and see all the names I've tried on.
