In the SIMPL OR Admin Site: https://app.simpl.org/efs/admin-ui/simpl.html#/users there are three states for registration on each user’s “Personal Information” page under “Registered”:

• If they have registered there will be a date for when they registered.
• If they have been sent the registration invite in the past, but didn’t respond it will be something like: “Last Registration Invite Sent: December 22, 2020, still waiting for registration”
• If they have not been sent the registration invite, it will say something like: “Last Registration Invite Sent: No data available”
