Not sure if anyone else is having this issue, but for the last several weeks (months?), I haven't been getting forum notifications until days after the relevant post. I'm subscribed to instant notifications for quite a few threads (Upcoming Shows, Kimmel, etc), and I now get my "instant" emails 2-3 days after. Same with PMs--my last received PM was on 5/11, and I just got the email a few minutes ago.
Are others having this issue?
