Allowing people to submit a form with minimal contact information is by design in NationBuilder. Once you have a person’s name and email address, it’s possible to reach out to them for more information – not so if they experience form fatigue and stop filling out the form without submitting. Some interesting study data on this is written up here – http://www.markerstudio.com/marketing/2011/10/how-many-fields-should-you-have-in-your-form/ 

In NationBuilder, action chains allow you to lead supporters through your most desired activities in a series of page types, which can include surveys with customized questions and response types. 

John, to demonstrate this I’ve set up activity chains from both my event and volunteer forms that lead to a survey page (those pages can have multiple choice, yes/no, and free text answers). You can check out the flow by using either form: 

http://www.wiredtoshare.com/volunteer_training and

http://www.wiredtoshare.com/volunteer

Both of these pages will lead to the survey: http://www.wiredtoshare.com/survey 

Adding a page in an action chain is in your page-specific settings – for the events page, which has a lot of functionality, it will be under Event settings > Advanced. 

If you are collecting private information on a survey, remember to uncheck “show stream” and survey responses won’t appear on the page. When using NationBuilder it’s important to note that many actions default to public unless the page setup is designed for privacy, or the supporter marks not to display their answers.
