This extension provides all the basic form elements in HTML, provides basic validation (required, some types, regexp) and provides a few basic actions, like 'hashcash protect' and 'mail' (the other two or 'validate' and 'message').
Because this extension has been build with the knowledge that you can never incorporate every wanted feature in any form system. It has been build to be extended to add new elements, new validations, new actions and new standard forms. Even the features it provides by default are created using the same framework, so there are a lot of examples you can choose from to build your own.
Version 0.15 has been released (supports UTF-8 in mail)
