+### Joining the hub and access (**Decided**)

+- **Any catalog can ask to join** the hub. It's hidden until a hub moderator approves it.
+- To join, a catalog must give **its own takedown and legal contact**. It stores the files, so the hub forwards
+  takedown notices and reports about its products to that contact (and can still block a product network-wide).
+- Two settings per catalog:
+  - **Visibility**: *public* (listed in the hub's directory and search) or *private* (not listed; found through an
+    invitation or link).
+  - **Membership**: *open* (any hub user can use it), *approval* (users ask, the catalog's operators approve) or
+    *invite only*.
+
+  Any combination works: a public catalog can still require approval; a private one can be open to anyone who has
+  the link.
+- **Seeing versus wearing** (proposed): membership is needed to get and wear a catalog's products; anyone can *see*
+  them on someone else (subject to age settings), or outfits would break depending on who's looking. A catalog can
+  choose members-only viewing, at the cost of members' items showing as defaults to everyone else.
