There are unit-level rooms with numbers that are more like clubhouse hangouts (that aren't super active, to be honest).
Then there is #on-demand posting where you can request upvotes from @sbi-booster. It will do a 25% upvote once every 24 hrs on a post by an account with 40+ units. The post must be between 15 minutes and 5 days at time of request.
If you support programs that also have 40+ units and you see they're not using it, you are welcome to request for their posts too.
Awesome, thank you for the explanation!
