what does "follow" mean?
I looked at the page Learn how to use Manage Subscriptions and use My Subscriptions. It was quite helpful, but didn't explain the basic term "follow". What happens when I "follow" something?
Also, I couldn't work out which community to post to - none of the ones in the list seemed appropriate. And there didn't seem to be any "Reply" option at the above link (though other people had replied). So I've used the "Category" (whatever that is!) of "Feedback about Discussions".
