Hi Gail, There are lots of behind-the-scenes taking place on the Connect Website, and something caused a glitch that caused some email notifications to stop.
Here's the fix:
Go to the top of the screen and click [or tap] the person icon.
In the drop-down box click "Profile & Settings"
On the Profile page, click the "Settings" tab
Scroll down to "Notifications...Activity Involving Me" and click Edit, then make your choices and click "Update"
If you want to receive the Digest, Click Edit, make your choice and click "Update"

Now, on the off-chance that this doesn't fix things for you, send a message to our Moderator (@colleenyoung) and she will take care of you!
Hope to see you back soon.
Sue
