Private categories

Wondering whether threads like this are better not being public?

@Graham, good question, would it make sense to have a CoTech/Private category and make it so that only people on CoTech co-ops could see the posts in it? It might take some work adding all the members of the co-ops so perhaps we would also need to make a member of each co-op a moderator?

I think I’ll split this into a separate thread.
