Well, for example, if we wanted contacts to be able to edit their profile.
One possibility is allowing them to select from a group of products they are interested in: Pianos, Drums, Guitar, Bass, Vocal ... We would like to track if they are interested, play, own products in each of these categories. Later we would use this type of information within the marketing application.
While this small example could be tracked using custom contact fields, I'm just wondering what the possibilities are with using only on-line forms.
Thanks again for your time.
