Hello Lemmy team,

Related issue: NodeBB/NodeBB#13075

NodeBB allows its categories (type Group) to establish follow relationships. This is strictly limited to Group-to-Group relationships and utilises 1b12 so that a category can mirror another Group's contents without the need for a user follow relationship.

When this follow relationship is reciprocated, then the categories are in essence synchronized.

NodeBB currently encounters a data did not match any variant of untagged enum PersonOrGroup error when sending a Follow(Group) to Lemmy.

Describe the solution you'd like.

It would be helpful to allow this sort of follow relationship; thank you for your consideration 😄

I know there is limited utility in something like this for Lemmy. In your case, your users subscribe to a community and their local lemmy instance hosts a local representation of that remote community via 1b12. I think that's great!

NodeBB elected not to do that, its categories are strictly defined, so the use case here would be two forums who want to each maintain their own category but have them synchronized.

Describe alternatives you've considered.

None 😳
