Each user account has its own watchlist. If you want to easily keep track of an article, you can see the most recent edits by adding it to your watchlist. To do this, simply click the star tab at the top of the page to turn the star blue, and the current page you are viewing will be added to your watchlist. You can add as many pages as you want to your watchlist. To remove it, click on the star again and the star will turn white again.
To see your watchlist click Watchlist at the top of any page of Wikipedia (you must be logged-in).
