The "Unwatch" feature is used to unsubscribe a question from your watchlist.
To Unwatch any question, go to that question and look at your menu on the left. If you go down, you'll find either "Watch" or "Unwatch" just above "Discuss" a little ways down. If you have set a Watch on it, you should see "Unwatch" in the menu. Click on "Unwatch" and your wish is WikiAnswers' command.
