Automatic email notifications about changes to your watchlist

Automatic email notification about changes to your watchlist is set to 'true'. If this annoys you, you can change the setting in your 'Preferences' (upper right - at bottom of first page there)

You can also "unwatch" the page by finding the gold star icon at the top (near to the search box) and change the setting for that page.

FYI, the watchlist is a list of pages you have edited or ones you have designated you want to "watch" via the star icon you'll see close to the search box in the current default skin.
