Enterprise and Super "Unlimited AffiliTest" accounts are including the option to active more users.
In order to active the users please follow the next steps:
Ask the new user to sign-up as free user.
Make sure that the new user is activating his account (he will get email from us).
In your Admin account, go to "manage".
Add the new user email and click "update".
Refresh the page - if the email is still there, you are ready.
