My latest creation that i've released under GPL 3 is a database-less contact form that only requires a server capable of running PHP and either php mail() function or an SMTP server.

You can see all the details about it here this page also includes a Downloads buttons which allows you to choose a version to download, just choose the latest version number and then follow the instructions in the README and INSTALL files to get it going.

I've tried to make it as easy to use as possible.
