So... I edited all my notifications to remove all email notifications and to use only popup motifications. For two days, I continued to get emails, not understanding why. I decided to actually read the bottom of the email notification and discovered it was being sent to me because I am apparently following the category a file was uploaded to.
I seem to remember checking a box during registration asking about being notified but... I really didn't want to be subscribed to a category, nor all of them for that matter (which I now find out I am). Now I have to go into each category to unsubscribe from them so I can stop getting emails about files...
We'll see if this stops the emails now.
