Welcome! This forum has a treasure trove of great info – Scouters helping Scouters! Just a heads up, though - all content, information, and opinions shared on this forum are those of the author, not the BSA.
To the Admins, Thanks in advance for your help, I have tried to have this addressed multiple times in the past by staff at two different councils, but it keeps popping up every 18mo or so. I can only see one account, but am told there are multiple, and i get the “another account is using the same email address” warning.
