Cut a deal with anyone, using a website to record the terms and conduct the negotiations.
For instance perhaps (ha) you can convince your wife to turn down the thermostat in the house in return for taking out the recycling bin every Monday. Or, more promisingly, maybe I can promise to Bryan Caplan that I won't make fun of his naive realism in return for his eating Pho with us twice a year. This site gives you a handy written record of the agreement.
Further below you read about training: "Make a sample deal with our interns."
The motto of this very ambitious site is: "Asynchronous Negotiation Favors the Underdog"
