A better solution is a curated list of tags users can attach to their posts.
I understand some communities wouldn’t want unrestricted tags, but it’d be nice if this was an option they could configure. It’d be annoying for say a gaming community to have to add a tag for every game ever, or a music comm every band ever.
I don’t believe this is mine or Mat’s first time making it onto this (I also only changed a number, hardly work).
