We here at object to all forms of government enforcement of intellectual monopoly. Unfortunately, we don’t live in that world. If we did, we wouldn’t need a copyright notice and such. That being said, by contributing to you are transferring all copyright from you to us. That’s why we are willing to pay you. We then retain copyright on all material contributed. Don’t contribute material copyrighted by someone else or else we will have to delete you account. In the long run we intend to put a paywall up, so anyone who wants access to the material you’ve contributed will have to pay us. We will then give some of that money to you. We aren’t there yet.
