District/multi-group visibility

If your group is part of a District or County that also uses Quartermaster, a District leader can get read-only visibility of your equipment — useful for oversight across several groups. Nothing changes for you until you choose to link up: the District generates a join code and shares it with you, and you enter it on your own Members page. The District only ever sees your equipment's inventory — name, category, quantity, location and condition — never loan or checkout detail, and no photos, and can never edit or check anything out. You can hide yourself from the District at any time without unlinking, or unlink entirely, both from the same Members page.
