HOVER your mouse icon over your name in the upper right hand corner and select: 1. PREFERENCES. Here, you can turn off email notifications of replies as well as your "watch" list. I recommend you turn off the watch list as well. Make your selections than SAVE. Hover it again, and then: 2. ALERT PREFERENCES. You can specify which alerts you get. Turn them all off if you want. Remember... SAVE. You can edit your entire profile by just hovering over your name and selecting the section you desire to edit.
