...online, I mean.
I have a number of different online names that I use for different types of forums. I tend to be Xanthe on forums that are book/reading related; I use another name on computer-related forums, and so on.
I realized, after I had replied to an IM on a board - might have be this one - that I signed it with an intial belonging to another of my "names" and that I had forgotten for a moment which name I used here.
I'm not one of those people who uses made-up personas with my various names - what you see is who I am in real life, no matter which name I use - so luckily I don't have to keep track of any false personal histories.
But I was wondering about the rest of you. Do you use different names in different places online? Do you create different personas? Do you ever forget which "character" (for want of a better term) you are supposed to be?
