First, I'd really like to say many many thanks for this terrific software. I've struggled for a few months or so with other discussion/forum freeware (some ASP and some not) and finally out of frustration, was fortunate enough to luck upon Web Wiz. It took about 15 minutes total to be up and running in a testing environment. It's the best! (I even made a donation.) 
Now having got that out of the way - my question is: I'm unable to delete a mysterious "guest" user. I say mysterious because the registration date for the user shows February 27 which was more than a month before even setting up the forum!!?? The "delete user" option which shows up in the window whenever I click on the username of any of the other testers is absent for this user. Please advise.
Gratefully,
Andy
