Did you add the featured tag yourself? Should that be limited to mods? Or maybe be automated by a user rating system. Can I tag @bart? Yes I can!
I did, and yes, the #featured tag is mod-only. I’m also experimenting with tag-groups; in the Art forum you can only add tags from a predefined list. I suspect it can help streamline the use of tags and prevent a growth of useless ones. What do you think?
I think limiting those tags is definitely for the best. Do the tag groups - I assume that’s a mod-only screen - always correspond to the categories? I can imagine tags being useful on multiple categories, but then you’d have to duplicate them carefully, and i don’t know what effect that would have if there was some kind of functionality were I can view topics with a certain tag across all categories.
I think that will be no problem. You basically define which tag groups can be used in a category, and a tag can be part of multiple categories.
