I have had a lot of questions lately about setting proper notifications for the community, and I wanted to post an update for you. Some of the options have changed (and gotten more specific!), so you'll want to check your settings to make sure they're set properly for what you want to be notified of on a regular basis.
When you click into your Profile > Account Settings, you'll see these options 👇🏼
My recommendation is to make sure that you have New activity in topics I'm following turned ON, and Notification from groups I have joined ON. (You will also need to turn on that first option for receiving email notifications at all.)
The rest of those settings are there if you need them, but updates for topics you follow and groups you belong to are the two most important.
Let me know if you have any questions!
