I've been getting instant notifications for years to a yahoo.com email address. This functionality stopped a day or two ago. I've been through all the CP and profile options and have a slew of threads I'm subscribed to, all marked "Instant", yet I see unread threads in my subscription folder which I never got notifications on. The telling bit was that I just actually posted in the "Introducing Prevx...." thread and received no notification email when someone posted just after me. Any help for this?
