What is the difference between the subscriptions of Single User and Multi User?

The Multi User version has more features than the Single User program, especially for the possibilities to add extra accounts. These features will be automatically added to your role once your changes are registered (after payment), but will be visible to the user when you logout and login again. The Multi User version allows you to login with multiple accounts at the same time. That makes it perfect for groups of breeders, like herd books and associations. The Single User version only allows 1 account to login to ZooEasy.
