Oops, missed one, use these instead
Auction Donation Updates

I have totally overhauled the auction donation system (and made fiddly
edits wherever I felt like it). As part of this overhaul, I have been
messing with routes. In the future, I'd advise you all to use
link_to_route not link_to, just because it took me a while to find all
of the links I may have broken, and I'm sure I missed a few.
