Hey,
I recently found a list of active FOSS projects that accept donations: http://djere.com/donate
I recommend all open source game projects add themselves/each other to this list, as well as
https://en.bitcoin.it/wiki/Donation-acc ... d_projects for bitcoin donations
and if code and art are DFSG-free, add it to the new wiki page Donation-accepting free, open source game projects too!
