Is this a use case for user custom fields?

I appreciate that this is not the normal use case, but I would definitely like to find a way to do this with Discourse, given how awesome discourse is. And I can get decently close–I create a tag with the API, and send users to the tag page that acts like the subforum page. The key piece i am missing is the ability to limit users who can post with that tag.

Discord would not work for these purposes, because of limits they have with integrating with apps. I’m not familiar with how I could integrate reddit with an app.

Are you suggesting that I could actually make this work with Reddit, or did you just mean that is the “type” of functionality I have in mind?

Either way, the key benefit of discourse as I see it is that it is a forum, not a chat. And the forum-like functionality is what I want here. I haven’t seen alternatives to discourse that could work in that regard, but I’m definitely open to suggestions.
