What is the "My Watchlist" for and how do we use it?

Underneath the question, hover your mouse cursor over the plus sign to reveal a menu. Click the option to add the question to your watch list.

Click the link to your My Q&A page. Scroll down to the bottom of the page where you see three tabs - My answers, My questions, and my watchlist. Click the watchlist tab, and then the link to the question to access it.

Questions will remain in your watchlist regardless of their status until you choose to remove them. You can either click the "Remove from list" option when you view your watchlist, or go to each individual question and repeat the process in which you added the question to the watchlist, but choosing the option to Remove question from the watchlist.

If there's a question that you really don't want to answer but would like to see what other answerer's have to say about it , then you can add it to your watch list. Click on the plus sign below the question(add to my watch list) to save it to your watch list to view later. You can view the question you saved beside of your My question, my answers(my watch list)

Hoover your mouse(cursor) over the + there will be a drop menu, the first one will be add to watch list, click it.
