Well, we did consider that use case when we added the ability to make private or restricted Reddits. I think it's a great way to do it, except for one thing -- you have to make a reddit account to get help. That would probably be barrier for some.

Also given that the reddit sorts prioritize newness, it may not be the best resource for support since there is a good chance some old posts might cover a common problem.

Overall there are probably better support platforms.

But using a private reddit for an internal support forum would probably work really well!

Reddit search is even worse than discord.
