I'm afraid I don't have any answers, Martie. If is were me, I'd probably wait another day, and not be too surprised if all your Notifications arrived suddenly and all together. Email servers do strange things at times.
If it hasn't corrected itself in the next 24 hours, I would probably get an email account at (shudder) yahoo or hotmail, just to see if that works. If it did (and I suspect it would), I would write AOL and yell a little bit. They may have recently turned on one of their infamous filters and be "protecting" you from what they see as SPAM. If you verify the Notifications can get to you through a free email account, then that should convince AOL the problem is at their end.
