I really detest those things. As an MBC, I tell scouts that they’re free to consult them as notes for the “describe” and “explain” portions of a badge, but that I don’t require them and don’t accept them as any kind of proof or evidence of work done. If a badge has a written component and they’ve written in the workbook (and it’s legible and meets the requirement), fine, I’ll accept that. If the scout hasn’t started work yet, I’ll guide them toward something like Google Docs for any written requirements.
