New post notification by e-mail not working consistently?

Hello FP moderators, I apologize if there is an e-mail directly to report problems with the board.. but I search for, and could not find such information easily. My problem may be easy to fix, but I am not sure. I usually log in and tag which posts I follow, and have in the past received numerous notifications of newer posts.

In the past week or so, I have received none. Is there anything I have to do once again?

Thanks!

temporary problems. wait please
