"Michael Clark" is not unique, so for most of my online interaction I go by "Iiridayn".
Michael Clark is an experienced LAMP (PHP) software engineer. Hobbies include security, fantasy, anime, and games. He plans to continue in school to get a Doctorate in Information Science.
Iiridayn is a programmer and social gamer - not a lone wolf. I use Iiridayn as my identity on the Internet primarily when I wish to interact with others.
Ged - originally named from "A Wizard of Earthsea" - is a large, scaly, black (off-green), fire breathing dragon. When I play as Ged, I fight to win. Ged was my first online identity, used for an AckMUD, "Shades of Evil".
Yevuard - name taken from same series as Ged - is a scientist and magic researcher. He is older and wiser than Ged, his brother. I use Yevuard more for scholarly persuits and draconic interests.
