Hi Joshua, this sounds like Slack’s Multi-Channel Guest and Single-Channel Guest user types, mentioned here: [Permissions by role in Slack | Slack](https://get.slack.help/hc/en-us/articles/201314026-Roles-and-permissions-in-Slack)

and they work like this:

Multi-Channel Guest: _" These accounts can only access selected channels, and they can start direct messages with the people in those channels. "_

Single-Channel Guests: _“This type of Guest account can only access a single channel and start direct messages with the people in that channel.”_

Sounds to me you’re looking for Single-Channel Guest? Perhaps it’d make sense to add those user types — if they’re useful in Slack, then perhaps in Discourse too.

(Perhaps a tips, then, for Discourse developers or plugin creators, would be to have a look at how Slack has solved this :- ) )
