Good luck, let us know if you need any help.
@JoeBuhlig helped us out, but hasn’t been very responsive since implementing the site. Worth reaching out to though.
We did try tagging too, as @HAWK mentions. It was more flexible but I ultimately felt it would’ve required too much user prompting to become a habit and have resorted back to categories now. Though if Discourse implemented a tagging feature like Apple has with a few buttons to select, I’d probably go back to it.
