I assume that means you didn’t get an alert about the weekly video but you did about Ling’s alert. If so, that means the Subscribe part in the My Account section/Notifications area isn’t on. And the box would need to be checked. Steven has some screenshots that show them.
The one for the weekly video is in the My Account button, then Notifications, then make sure the drop down menu says “Subscribe” and that the box below it is checked. Then hit Save.
I got some of mine not all, but what I did to get any because I wasn’t. Was I went in and turned all my subcribes to unsubscribe saved them logged out them logged back in and changed them to subscribe and saved them and logged out. And I got many more but I believe I am still not getting all but I like that I am getting many more.
You’d want to keep the forums showing “Unsubscribe” and the My Account/Notification area to “Subscribe”, box checked and click Save. After that, the problem would not be on your end and due to outside forces.
