Creating a user group will allow you to select users and put them in a group for form assignments. This way, instead of selecting an individual user for every form you want to assign, you can simply assign the entire group the forms. To create a user group, please follow the instructions below.
STEP 1: Hover over the Users Tab (A) and select User Groups (B).
STEP 2: Click the New button.
STEP 3: Type in your user group name (A), and then choose the users you want in the group (B). Click Create (C).
In Form Assignment, you will see the user group you created in the list. You can allow them to collect or view, just like any other user.
