Hi psycho slinger...
I don't think that the email field is really used for anything other than bookkeeping, and so other members can look you up. From an administration point of view, it is nice to have a little bit of accountability.
A simple option would be to get an email account! I'm surprised actually that AIM doesn't automatically saddle you with one, but free email is dime a dozen these days. Hotmail, gmail, Netscape, Yahoo are some big ones, plus a few thousand (hundred thousand?) others...
I suppose the other question has to be "
how on _earth_ do you survive in this day and age _without_ at least one email account? "
I'd love to be that primitive.
