When you click (using clicks/searches) all of the clicks on the list, if you refresh the screen it will change and show all of them complete, you don't have to participate. Also, at the top of the screen, you will see the total number of points and cash you have, if you have lots of points but no cash, click on convert points and for every 10 points you have, you will get one cent. It adds up faster than you think.
