I'm sick of getting dozens of E-mails a day because other people are posting in threads.. I don't know how got subscribed to hundreds of thread, but there is no need for this. How do I unsubscribe?
When you first sign up, it's usually set to automatically sub to a thread you reply to, that's how it was on mine and I got the same thing! You can go here, check the box to select all your threads and use the drop down menu to Delete Subscriptions:
Then go here and in the 2nd category ( Messaging & Notification ) you'll see the subscription option, I have mine on Do Not Subscribe which allows me to pick personally the threads I want to subscribe to and how often I want to be updated.
