P.S.

I am only in favor of maintaining the guest user option as long as it can be done without the site users getting my IP or my email.

It might be helpful to explain briefly on the "how to" pages (the privacy issues page perhaps?) just what the technical differences are between posting on a publicly accessible website discussion forum, a Usenet discussion forum, or a private mailing list.

It seems to me that an awful lot of Mudcat users don't know or understand (and therefore can't appreciate) the differences regarding identity affixed to an email account, identity affixed to a log-in name, identity affixed to an IP, etc.

It might go some towards ending animosity between member users and guest users.
