What does "awaiting confirmation" mean?
You may have noticed some users have "Awaiting confirmation" showing in the confirmation column of the Users menu in the Manage workspace. This status simply means they have not verified their email by clicking the link in the account confirmation notification sent when they registered.
The confirmation notification may have ended up in their junk or spam folder or they simply forgot to go back to their email and click the link.
As a grant manager, you can confirm these user accounts manually by clicking the Confirm link.
