Can I use your signup form with my own custom list database?

Yes!

In order to do this, use the Settings button in the form builder and adjust the custom Post URL to a page you have created to handle the data input. By leaving this blank, the default SimplyCast Post page is used to save the data to a list in the SimplyCast system.

We suggest this setting be left to more advanced users, as all of the post information must be properly handled on this page to ensure proper data collection.
