That's fantastic, thanks so much. I hadn't imagined that it would be so complex.

Don't want to push my luck, but I have 2 more related questions:

1. how can I allow HTML in the extra fields? it appears to parse it out by default

2. how can I change the extra fields to a text box, instead of a single line field? I found the tpl file to edit in /modules/extra_fields, but when I change it, it does not show the existing text when I save or go back in to modify. It appears to be saving ok, just not refilling the form field

Thanks again!
