Geoforms

Geoforms is a WordPress plugin which makes it easy to create and manage forms.

This plugin avoids problems that plague other wordpress forms plugins for one simple reason: the forms and form fields are created and stored separately. Instead of being tied to forms, the fields are tied to the data. This allows you to add any field to as many forms as you like. You can then use the same field in that same form, or the same field in any another form, to update the same data.

Other features that make this plugin unique:
You can add fields in bulk amounts.
You can easily create forms which are based on the results of other forms.
