Contributors' rights and obligations

If you contribute material to World66, you thereby licence it to the Creative Commons Attribution-ShareAlike 1.0 Licence. In order to contribute, you therefore must be in a position to grant this licence, which means that either

  • you own the copyright to the material, for instance because you produced it yourself, or
  • you acquired the material from a source that allows the licensing under the Creative Commons Attribution-ShareAlike 1.0 Licence, for instance because the material is in the public domain or is itself published under the Creative Commons Attribution-ShareAlike 1.0 Licence.

In the first case, you retain copyright to your materials. You can later republish and relicense them in any way you like. However, you can never retract the Creative Commons license for the versions you placed here: that material will remain under the Creative Commons forever. In the second case, if you incorporate external material licenced to the Creative Commons Attribution-ShareAlike 1.0 Licence, as a requirement of the lincence itself, you need to acknowledge the authorship and provide a link back to the network location of the original copy.
