We are currently working on creating an exchange where contributors automatically can sell their Profit Points to get cash faster. In the meantime, this will be a manual process, where you can write to the owners and we will send you cash via PayPal within 24 hours. The exchange rate will be the one stated on the website at the time of you initializing the transaction. If PayPal is not an option for you, then we will work something out.
One thing should be noted about the exchange. We believe that it is the people who create things, who should make decisions about it, and not some capitalist, who can buy the whole thing. In other words, the purpose of Open-Org.com is to create a meritocracy and not a plutocracy. This means that if Profit Points are sold, they will loose their voting rights.
