Join/Leave/Search Lounges

Our use case would be a server for our university program association where students can discuss between each other.

As an example, we would like to have a channel per course, and many others depending on the interests of the students (ex: projects, parties, etc.). This means that there would be many channels for which many students wouldn't be very intersted in, and which they would rather simply not see than them being just muted: there are hundreds of courses, and a student while usually take at most 5 by semester and probably won't be interested in most of the subject of interest / activities organized.

This is the only feature refraining us from moving from Slack to Discord.
