Require email address for ‘guest’ post submission.

Hi Guys,

I’ve been trying to figure out a way for users to input their name and email address when asking a question – but so they don’t have to register on the site but can get notification when someone replies etc etc.

This is a private Q&A forum so SPAM isn’t really an issue.

I’m sure this must be possible but can’ t figure out how.

Can anybody help?
