You do not need to do anything special, just checkout as you normally would do. We will part 15% of the money when some bought a WPDollarPlugins membership and will donate that amount to a random charity or act per month. We will update the amount WE have donated in the last 6 donations here. And also, at the bottom of this page, you can see the total donations WE have raised along with the names of the membership holders. (Or if you want to donate to a charity directly, please scroll down)
