Thanks for downloading the Anti-Spam Guestbook Script.
If you use this script send me an email, always nice to hear from users.

If you do come across a bug or a problem send and email to nospam@combatarts.ca
and include as much information as possible about the error. Server OS , Webserver
 name, any logs or exact error messages etc.

To see the changes for this version scroll down to the bottom of this file.

The main files are in the same folder as this file. They should be:

dbase.pl			<=Library file used by both scripts
Zone.pl			<=Timezone functions (thanks to Grahm Barr)
ColorPicker2.js		<=Javascript color picker ( thanks to Matt Kruse http://www.mattkruse.com/ )
