1) I can have my form populate MC groups, not just MC lists, can't I? I had assumed so, but saw another thread that I thought suggested otherwise (it's more likely I just didn't understand the question).
2) more importantly, I need to know how MCs "updating preferences" would work with this form. Which is to say, if a user who wants to change their selections clicks "update my preferences' in MC, can I send them back to this form (and if so, how can I pass their existing settings back to pre-populate the form with them)?
Thanks
