In CloudForge, user accounts are specific to an Organization/Domain. A user having an account with Domian - B, cannot be added to projects without having a different user account created for them in Domain - A. An account owner can allow users from another Organization/Domain to create an account by
*1. Sending an invite to their e-mail address. Where users will be presented with a link to a signup form to create an account for themselves in Domain - A.
*2. Owner can manually create new user accounts from Admin -> Manage users section in the CloudForge UI.
