New mandatory radio button registration field

[imageconstrux]

I looked over at VB.com and searched like crazy over here, but have not found what I'm looking for.

I'm wondering if/how to go about adding some defined registration fields. I want them to be more than mandatory, I want there to be a radio button selection, much like the button selections for registration fields now.

The nice folks at VB.com suggested there may be a hack like that here, but like I said, I'm not having luck finding it. Can anyone point me in the right direction?

Thanks,

Jeff
