Designing a profile form for profiles in Quota X, and a different form for profiles in Quota Y
Using Jamroom
Unless I'm misunderstanding this all can be done with the Form Designer as it stands. In the profile update form, click on Form Designer button and start adding in all of the above fields, allocating each one to the appropriate groups and quotas (where there are duplicate fields for quotas, hold down the cntrl key and select multiple quotas, so, for instance, Website 1 and Website 2 are visible for profiles in quota A and B whilst Website 3 is only visible to profiles in quota B).
If any of this entered data needs to be visible on a profile page, you'll need to edit the profile template(s) to now show it. Profile privacy settings will override things though, but only in that if a profile sets his privacy to 'followers only', or 'private', only followers and admins will see the profile anyway!!
Are any of these fields needed to be shown in the signup form? If so, we would need to add these fields to the User Account form and the Signup forms, not the profile update form.
