Tectonic Designs: Guestbook
This is a guestbook program that edits a web page and is not generated by CGI on the fly. This means that when users view it, it comes up much faster! In addition, it can block cussing and bad language, block HTML, send e-mail when signed. Verifies e-mail and http addresses when entered, limit the number of entries in a file and support as many guestbooks as you want.
