I just got about 10 email notifications for every thread I had posted in recently - eh? That didn't happen before. I think there's now a gremlin in the system 
I have a theory..
I think notifications had stopped working (maybe only some of them.) Some of us went and fiddled with our settings. Now notifications have started working again, and the ones - or some of the ones - that hadn't arrived have now arrived.
I had an email notification for your last message to me, FW, and then, later, the notifications for the earlier ones all came. If you went and changed a setting recently, you may now be getting notifications from threads in which you post
