CreateSpace continues to work to improve the ease with which its authors can use its various services, in this case, tracking monthly sales. In the past, tracking sales meant going to the author's Member Dashboard, logging in, clicking on the View Sales for the Month of... link. This would show the sales for just that title.
In order to view sales for every title an author published with CreateSpace, it was necessary to jump through several more hoops in order to see all the sales of the author's list. Now, merely logging in to the Member Dashboard will pull up accurate, up to date sales records for all of an author's list.
Kudos to CreateSpace for making tracking sales easier for its authors!
