I think it would be a great idea to develop a Firefox extension which adds a referral code to Amazon.com purchases that sends the referral fee to the Mises Institute. Miro, an open-source media aggregator project, already does this. Take a look: http://iheartmiro.org/
I would gladly install such an extension, and I think it would be a terrific way to help out the Mises Institute!
Edit: Oh, and if this is the wrong forum to post this, can a moderator please move it to the correct one? Thanks
