I’m on another forum that also uses Discourse and in case if anybody’s wondering, this is what a ‘Regular Lounge’ looks like:
(The forum’s also formatted a lot differently than this one)

If you’re wondering what goes on there, its pretty much less active version of the main forum with fewer but more polite users of the forum.
For reference, this is what the main page looks like without the lounge.
Like what @GBHS_VEX_Member said, there’s really no point in having such lounge like this on this forum, since not everybody can see it. Plus, what would you even put in there that you wouldn’t want new/random people to see?
