By contributing material to LeftLeftUpUp, you agree to license it to the public under both a Creative Commons Attribution-ShareAlike (Australia) licence, and the GFDL (with no invariant sections, front-cover texts, or back-cover texts). By contributing, you also agree that attribution should be made to the LeftLeftUpUp wiki, and not necessarily to yourself as an individual author.

In order to contribute, you must be in a position to grant these licenses, which means that either

• you hold 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 both the GFDL and CC BY-SA, for instance because the material is in the public domain or is itself published under a dual GFDL/CC BY-SA licence.

Because LeftLeftUpUp is dual-licensed, you may not incorporate material which is licensed under either the GFDL or a CC BY-SA licence but not both.

If you incorporate material from another site which is dual licensed under both the GFDL and a CC BY-SA (or CC-BY) licence, then you must acknowledge the authorship and provide a link back to the original version.

By contributing to LeftLeftUpUp, you are irrevocably licensing your material under the GFDL and a CC BY-SA licence. You can never retract this licence, which means that everyone will always have a right to use, republish, and modify your material.
