Build forms with html, send notification emails or use them in your application
Most webform plugins let you create forms interactively. They have many options, some even let you insert PHP code. But in the end they all create some html.
The idea of this plugin is that it creates basic html which you then can modify for your needs. The plugin sends emails to the visitor and the admin, for each of them you can create a template containing the field values. And it provides the hooks you need to create your own functionality.
