This is my first post here and I'm hoping that somebody out there will be able to help me with a problem I've been having for a while now.
I need a Guestbook for my website and, despite trekking through nigh on a million search engines, cannot find one which suits my needs.

Basically, I need one for which users must register before they can leave a comment. I know that's not how Guestbooks usually work, but I really need one like that.

Oh ... er, I'd need it to be free as well.

If anyone can help in any way at all, I'd be more than grateful.
