The Gbook guestbook module for CMS Made Simple™ has a built-in anti-spam feature. It uses the b8 statistical (Bayesian) spam filter. At one of my websites where I use the GBook module I noticed spammers are getting more clever trying to by-pass the filter and it leaves me more work checking ham or spam...

I found a really simple method to hide and show the form. When there is no form, a bot can't fill it in...

  How to use

Open the guestbook content page in the Admins page-editor and set WYSIWYG off in the Options tab.
Replace the GBook tags with the following code:

Note: Change the URL's in the code above to the one of your guest book page!

Basically it takes these steps:

• Read the "showform" parameter from page URL
• Only show the form when having the showform parameter in the page URL and the value is 1
• If not show the message button, when clicked it reloads the page *with* the showform parameter
• Show the current guest book entries

Afterwards you can always change the parameter name and/or the value. Or even set the date ( {$smarty.now|date_format:"%e"} is now 15 ) as value, so it changes every day... Let your imagination run wild :)
