I know the site had some issues a week or so ago, but in the last day or two (that I noticed), I am getting email notifications roughly 21 hours after a thread I'm subscribed to gets a new reply, or a new PM.

 

I have them turned off, but many sites send you notifications at the end of each day. Otherwise if it were a big thread, you'd get 50 emails a day. PT.net may be the same way.

 

This one came immediately...go figure...

I have mine set where it will send me a notification as soon as someone replies, but it never would keep sending them. In other words, just one email until I click on it and check the thread. I've never had issues in the few years I've been registered member.

 

I have notification of pms and I usually get notification ASAP when I get a pm but lately mine is hours behind as well
