Talis Elevate accounts are created by Talis. We then send an invite URL to the new user. This is a one-time login URL that creates your colleague's account so they have teacher permissions.
If you have a colleague who would like to use Talis Elevate on their course, please log a support ticket via the help button found throughout Talis Elevate. Please send us their name, email, and subject discipline so we can get in touch.
Please note, if you have sent a colleague a link to one of your resources so they can have a look, they will have entered the system with student permissions. It is very important we change their accounts to teacher accounts, so their activity doesn't impact your resource and module analytics.
