Ron,
I just started receiving them again with the posts that you and Warren made. I have already checked my traps and spam filters and they were not the problem. The ISP told me they weren't receiving anything yesterday as I told them it worked the first day and then just quit. I never received any last night, but suddenly now they seem to be working.
EDIT: I just tried sending myself a PM and an E-Mail and I received notifications for both of them, so whatever it was that was blocking mine seems to have cleared up for now at least. I hope that it stays working as I hate trying to work with my ISP. They insist on only working with the site administrators, but one of them knew me and he did check for me yesterday.
Thanks for checking,
Ron
