I tend to change avatars a lot, mostly when I'm doing a story in the Writer's Corner or when I try something zany in the llounge. For a while, i was all pandas, which where the pandalol (

) comes from. Then llamas, which is where the llounge spelling comes from. The thing about avatars that I like in changing them, is that they puctuate the mood I am playing with.
As for my name, Isaac Asimov wrote some stories about his home life in which he tagged his wife, a psychologist as a pshrink. As an homage, when I was on Compuserve SF SIG, I came up with pshrynk, since I'm a psychiatrist and there had to be some difference there. It has been my handle since around 1989.
As for my real identitiy, anyone with a few moments to waste can look up all the pshrynks in La Crosse and make a pretty good guess at that...
