I found the problem. I switched my email address from the Yahoo one to my work one and received 2 notifications overnight. The email domain that they came from is gmail.com. Over the year that I was inactive on the forum, I had received so much spam from someone with a gmail address that I had blocked that entire domain so any emails that were coming from here were blocked and never allowed through.
sorry for hijaking your thread sarah
some of the most informative threads on here are the ones that go a bit off OP
