In my profile I chose the options in bold:

Forum subscription preference

1) Notify me whenever a message is posted
2) Notify me only when a new topic is posted

Thread subscription preference

1) Notify me whenever a message is posted
2) Notify me once per thread until I visit the thread again

I do believe I made the right selections. -or- am I mistaken? I was receiving notification up until I updated my profile a few days ago. No, I don't remember what it was set at prior to updating. No, I don't have a spam blocker. Please help. Thanks.
