Beta Email Signup Form

This is a very simple, yet stylish, form for your website where visitors can enter their email address (and name if desired) to be added to a contact list. It uses AJAX to submit and validate email and will also function if the user has javascript disabled.
Installation is quick and painless. This form does not require a database to function as it will create and store input into a CSV file.

In a nutshell:

Very easy to install and customise
Room for name field as well as email address
Basic email validation included
Works without a database
AJAX form submission but it does not rely on javascript
Secure password protected CSV download (live preview allows public to download only for testing purposes)
