I am not 100% sure if this would work. But I think @codinghorror might mean something like this.
Change site permission to not require Login.
A category you want viewable from outside set security to Everyone See.
For all other Categories set Security to:
- Trust Level 0 See/create/Reply. - Note 1
- Repeat for Trust Level 1 to 4
Note 1:
The first Security setting for Trust Level 0 could also be set to just “See” or “See/reply” With About Category telling a user needs to upgrade Trust level to X before can Create Topic and/or reply.
- This alternative may work as well to keep login required and allow lower trust levels to view a category but not create and/or post until they upgrade trust level.
