If you only want specific users to fill out a form, instead of every registrant, the process only takes a few steps.
To begin, make sure you are in the User Management interface by selecting the “Users” tab located to the right of the Regpack logo:
Click the checkbox to select the users who will receive the additional forms.
Click the "Add forms" option under the "Forms" section:
Choose the form(s) you would like to add to their system and click "Add (1) Form(s)"
