I'm forwarding this information directly to the list.

It's from Canonical/Ubuntu about their donation during download screen. They say:

* 1 in every 500 downloads results in a donation (0.2%) * People donate what your default is normally * There are lots of complaints about the download format * They plan on changing the download screen to a thank you page

This is important data for us, because I feel the good will of our users is important for us and noting to large amount of complaints is important for the design.
