There are not hierarchical permissions in NodeBB. If you would like to see hierarchical permissions, you could open an issue on our Github page and request such a feature.
I do believe we have a way of copying permissions between groups, so that could help you out in doing what you want.
One of the things im starting to like on nodebb is the ability to create groups and have a little something for them like the header and users posts.
If everything is over modules, why its not on widgets? I would love to have change some stuff on the fly like on custom pages plugin.
Ex: show a particular category posts for that group.. show a possible calendar (this plugin this works?!) and so on...
Yeah it might make more sense to use slugs instead of the actual group name when storing the key. Right now when you go to the group page you use a slug in the url and then the code grabs the group name using that slug to load the correct group's data.
I just tested to create a new group and following two issues occured
bug: using svg-images for header works fine until "save" gets pressed. save responds with "error".
feature-request: I'd like to set the background-size to contain and center the position.
