Useful information for anyone doing donationware services.

Since August, a team of dedicated staff members and volunteers has worked to develop the fundraiser for this year. We committed early to radical and full disclosure of all the data we had, in keeping with the spirit of the transparent nature of the Wikimedia movement. We quickly identified three major points in the donation process that were "levers" we could pull to optimize the process: banner messaging, banner design, and landing/donation pages.
