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.
The best way is to ONLY do online registration - that is fixed - if you are making accounts for scouts with paper applications - make the account using the paper app so everything matches so they meet up
Unfortunately online registration didn’t work and the council suggested a paper app. The family tried for weeks to get the online version to work. Thank you for merging them in scoutbook.
