at the top of the page by the search box you will see "subscriptions", click that and it will take you to a page with all your subscriptions and near the bottom of the page you will see a little box you can check, that is the button. it was a little confusing to me too but i got it and now things are normal *knocks on wood*
Ok, will go try that..but in the meantime, just got..one...message! From way earlier today. And only one, when there have been many. I will go try that, log out again, then back, and see what happens. Thanks!
