I created some Custom Lists in my Watchlist. How do I see what items are in the custom watch lists?How do I delete the list if I no longer want it?

Using a desktop browser, you can reach your custom lists by going to your Watch List page and clicking on the large Watchlist heading at the top to reveal a drop-down menu of all your custom lists. From each list other than the Watch List, you should see a link to delete the list in the upper right corner. The Watch List cannot be deleted.
