After being spammed to death I was forced to pull the 'Contact Me' page as I had got sick of the amount of emails I was receiving.
I had improved my script to stop the bulk of automated form submitters by using sessions, I had also managed to fix a glaring security hole within the script that allowed the injection of mail headers and allowing Jo Spammer to use my script to send to anyone they want!
The Contact Me page has now been re-enabled thanks to a nifty script from Edward Eliot. The script is his PhpCaptcha script, which allows easy implementation of those images the display a string of text in weird fonts, forcing you to type in what you see before you are able to successful submit the form, aka CAPTCHA. The instructions are very easy to follow and understand, so I won't bore you with them here, please go to his site if you what to find out more.
A link to the download of this script and instructions on how to find it can be found here.
