So, turns out a lot of previously VERY ACTIVE people didn’t realize this, and it was something that plagued the community after we passed 10,000 members, but the ability to turn Notifications on was re-enabled for large communities a while back. On the upper left hand side there’s a little bell - click it and turn notifications on!
Downside: It spams your gmail. Upside: gmail now filters these into a ‘social’ folder so you don’t get your phone spammed with noise and they’re largely unobtrusive.
So, enable those notifications! The more active people there are, the more useful this community is to everyone!
