Accepting an invitation to become an administrator
If a Landscape account owner wants to enable you to use Landscape to manage the computers registered in their account, they have to send you an invitation.
Accepting the invitation and creating your own Landscape login takes just a couple of minutes.
Step 1: Follow the link in the invitation email. If you already have a Launchpad account, log in using your Launchpad username and password. Otherwise, create a new Launchpad account (help on creating a Launchpad account).
Step 2: Once you've logged in using Launchpad, simply complete your Landscape registration and you'll be ready to start managing computers in the Landscape account.
