Add members easily in the My Account area.
While logged in, go to the “My Account” menu and choose “View Account”. From there you will see an option to upgrade or add seats to your account if you are a group admin, or have a single subscription. On the upgrade page you will see a box showing two questions- “How many seats?” And “How many are KLplus seats?” The numbers in the boxes indicate how many of each are currently associated with the subscription and when you increase either number you can click the “REFRESH PRICE” button to see the cost of the change.
