I was just wondering if this behaviour is possible in NationBuilder: A site I'm working on does not require a login layer. So, when a visitor fills in a volunteer form, we want to capture their information, but not log them into something they need to sign out of. 

Presently, "filling out a form logs them in." I think it's okay that sharing a page logs them in, because this is how we can capture a visitor's social media information.

But I would not like to log them in just because they filled out a volunteer or donations form.

Am I missing something about why keeping them logged in or semi logged in is a good idea, if we don't use a lot of social functions like leaderboards?
