Cont. FP 2002 & Discussion Form

This is a continuation of an earlier post that I reported as resolved but is
not.

I used FP 2002 to build a discussion forum (mostly playing around) and so
far so good...EXCEPT...then I try to post an article, I am prompted for a
password.

On my WEB server, using IIS and FP Extensions 2002, I have my default
IUSER_WIN2KSERVER set to browse the site and only Administrators can Author
it. Having looked at all security settings, I feel sure I need to make some
minor modification to make this work, but I don't want to give everyone on
the planet access to Author the site.

Anythought?
