Today when I went to download an updated version of the Arduino IDE (the Windows installer, I think), I figured I'd make a donation. After the PayPal donation completed, I was redirected to a generic Thank You page. I was sort of expecting either the download to start, or a link to complete the download. Instead, it's a matter of navigating back to software, clicking through, etc - and then getting asked to make a donation again. :) Not an ideal user experience (esp since I got to the download via Google search, so hadn't previously navigated to software from the home page - happily, the site is pretty simple to navigate).

I was not logged in at the time, if that makes a difference.
