Advanced Guestbook versions for Content Management Systems:

TPK Guestbook 3.1.1 (PhpNuke Version)
See it at: http://www.tp-krefeld.de/modules.php?name=Guestbook
Download it at: http://www.phpnuke-module.de/

Nuke Guestbook 2.0.0 (PhpNuke Version)
http://www.codec-download.com/modules.php?name=Guestbook (English)
http://www.rideo.de/modules.php?cid=18&d_op=viewdownload&min=30&name=Downloads (German)

There are probably more PhpNuke versions out there.

Html code enabled does not appear to pose a risk, but that could be because the admin is using Sentinel (a must-have for PhpNuke Security!).

http://www.3hc.co.uk/studentsupport/ (PhpWebSite Version)
Note: Some CMS versions are based on early versions of Advanced Guestbook (not 2.3.1), so you should investigate re: security. Mods listed here may not work with these versions.

Upgrade 2.3.1 to 2.3.4
