We have recently made a minor upgrade, moved to a new server, and added https support. If you notice anything unusual, please feel free to let us know.
If you stopped getting notification emails, the emails are either in your spam folder (please mark them as not spam), or your ISP blocked our new server IP, in this case, I have contacted your ISP to unblock us. You can do it too and get a faster result as a customer, just tell your ISP that emails from forum@accessforums.net (server IP is 184.95.63.10) are not spam.
If "New Posts" or "What's New" doesn't work as expected, please do a "Forum Actions -> Mark Forum Read", it may set the things straight.
