At AdStage, you can add an unlimited number of users to your account (trial users are capped at 20 users). Here's how to add a user:

Step 1: Hover over your user icon on the bottom right-hand side of the page and click on User Management.

Step 2: Click Invite User.

Step 3: Enter the email address of the person you'd like to invite.

You can also remove users in User Management, as seen below. 

Note: Before removing an account, please ensure that relevant dashboards and automated tasks are duplicated so they will continue to run as expected after an account removal.
