This is a great hack, I've had it installed on my board since the beginning. I'm hoping to tweak it, though. I have drop-down boxes for required fields, and the default is the first field in the list. If a user doesn't actively select a different option from each drop-down, the default is what ends up as part of their profile. I'd like to avoid this issue, forcing new registrants to actually select an option. I would imagine this would involve adding an extra field for each drop down that says "Make a selection" - that part is easy.

What I'm wondering how to do is, how do I get the system to return an error if they do not make a selection?
