I have Group A with permission on Category A, and an independent Group B with permission on Category B. Now I need a Category AB, and users must be members of both Group A and Group B to see Category AB. Membership in Group A and Group B is independent- there is no relationship between them, and users opt-in to each.
- Logical-OR would be easy- just add Group A and Group B under category permissions.
- Logical-AND would be easy if there was a relationship between Group A and B- just make a subcategory.
Neither of those helps me. The only solution I can think of is make a third group AB and have a plugin that populates it with users who are members of both A and B. Any other suggestions?
