They don't show on profiles and members cannot edit their answers.
The answers are only relevant to staff approving their account.
The problem is that whether I put these questions under Preferences or Personal Details, current members are forced to answer them because the fields are required. Since the fields are new, no one has answered them.
That means a member of ten years would be forced to answer 'how did you hear about us?', etc when updating their preferences or profile.
Is there a way around it? Would setting those questions to display:none in the css work? Or is there a better way of handling it? It would be nice to have a category just for registration questions – is there an add-on for that?
