"extofer" is my web handle. This pseudonym has been with me since the moment I laid on a Black and Green screen over telnet. I often am asked, why "extofer" or what does it mean?
When I thought of it, I was thinking, "If X-mas (pronounced exmas) is short for Christmas, can X-topher be extopher". So I dropped the 'ph' and spelled it extofer. That is the story, now I'm on the web and have been even before extofer at juno.com.
