We could make an effort to make this community more active. For example one could have as a goal to create a new post every day, just anything that’s interesting or useful, such as news or links to tutorials etc. If only a handful of people were doing this I think the community would pick up in a relatively short time.

Also I just found this community today, because I searched for “home cinema” when looking for interesting communities to subscribe to after creating my account… Not sure if there’s any solution to that
