If you see an email address in bold and red on the "Review Resellers" or "Review Internet Resellers" page, then that means the reseller has already registered on the reseller portal, and this is probably a duplicate registration.
The red is a warning for the gatekeeper to review the other registrations for this reseller and make sure they are not approving a previously denied reseller or approving the same reseller twice.
To review the other statuses:
Select "All Registered Users" in the Display drop-down.
Select "Email" in the second drop-down.
Then enter the red email address in the text box and click "Filter".
You will see all the usernames and their statuses associated with that email address.
