Silentum FormSend is a basic PHP mailing script which is great to use as either a "Contact Us" page or a feedback system for your site. Unlike other forms, this one requires absolutely no MySQL, and is sent through a single PHP file. It uses a simple form to send user comments to a specified email address, and can be easily set up in a matter of minutes. It logs the IP addresses the messages are sent from to prevent abuse, and has settings as to which of the four fields to require, and which to leave optional.
