This addon prevents multiple emails from being sent through the forms on the site by adding a hidden challenge. Sending
emails through the forms is a favorite thing to do by spammers.
This has traditionally been handled by Googles Recaptcha code but that causes too much of a challenge in many cases and can
easily frustrate your customers. This code doesn't present a challenge for the customer at all. The checking is done without
the customer even knowing it.
The code will work in any version of oscommerce but the instructions are just for the Community Edition and just for the
contact us page (due to time constraints).
