The Users area of Settings lets administrators manage ThinkUp users and activity.
TODO See a full list of users, when they last logged in, activate/deactivate user accounts, etc
While a ThinkUp administrator may not want to keep application registration open to everyone, she might want to invite a specific individual to register for an account. To do so, click on the “Create Invitation” button. ThinkUp will provide a unique, single user registration link which expires in 7 days. Copy and paste that link into an email or instant message to a user to invite that person to register for an account.
The invitation link is good for one-time use, and expires after 7 days.
