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.
MJ registered her son in 2017 with a paper application. The registrar create a MID for her at the time her son was registered.
In 2021, she used a new my.scouting.org ID to create an application for her son to transfer him to your troop. This generated a new MID because the system did not find her old ID.
I can clean it up but it will be later today before I can get to it.
So just got off the phone with her. She tried but she got a message of member id not found. I am not going to worry about it as it is working and I am happy. Thanks so much for your help.
