Well, @GR8FL, I did a bunch of testing. I’m not positive, but I think something had gotten broken in the notification system. I was trying on a test account, and was not getting emails. It IS possible it is still broken for gmail accounts, but the notifications got through on my last attempt using both the @ notation and the Notify me of follow-up option from under the reply box.
So, I think you should see a notification now, maybe 2 if you also checked the notify me box. But if you don’t, I’ll try more tests to gmail accounts. You should also check your spam folder.
