Is anyone else noticing that immediate e-mail notices are running at least an hour behind the time when messages in threads you're subscribed to are posted? Kinda makes it hard to keep up with discussions I'm following.

Joe, when you have a moment would you please be so kind as to look into this? Thanks.

"Immediate" largely depends on what how busy the site is.
things can and do take up to several hours to trigger at times.

There is nothing to check into.
