I want to add another "vote" for this.
The abiity to add/remove data elements from the form (and edit field labels in the UI) would be MOST helpful. I have many applications in mind where things like address and phone number would be essential, whereas ICQ and YIM (etc.) fields are useless and in fact in the way. For example, I am putting together a reunion site and would like to be able to collect more detailed contact info. Check boxes/radio buttons, too ("Are you attending?").
Xoopsmembers + newbb could be a nice customer support tool with a few of these tweaks, too!!
