Only the Account Admin is able to manage that. If you do not see the following options, you’re not the Account Admin.
To add a new user, click Account & Settings
button across the top of your account, then click
Users.
Next, on Users page click the New button.
On the New User page fill out the appropriate information, including desired
user role, and scroll down to click Create User button
to add it to your account.
You have successfully added the new user to your account.
And you are done! The newly added user may start using Yardman now.
