I thought the same thing. We could have a set like that, maybe another with tags like problem area, winterization, upgrade projects, etc. and yet another by model - N22, N26, etc.
It looks like we can restrict tags by category, so we could have the full taxonomy for the knowledge base, but a different smaller set/subset for General.
What do you think about having another category for “How To and Advise”? To keep everything from going into General.
