To avoid future problems, here is a copy of the CC License agreement.

The CC (Creative Commons) License -

How does a Creative Commons license operate?

Creative Commons license are based on copyright. So it applies to all works that are protected by copyright law. The kinds of works that are protected by copyright law are books, websites, blogs, photographs, films, videos, songs and other audio & visual recordings, for example. Software programs are also protected by copyright but, as explained below, we do not recommend that you apply a Creative Commons license to software code or documentation.

Creative Commons licenses give you the ability to dictate how others may exercise your copyright rights—such as the right of others to copy your work, make derivative works or adaptations of your work, to distribute your work and/or make money from your work. They do not give you the ability to restrict anything that is otherwise permitted by exceptions or limitations to copyright—including, importantly, fair use or fair dealing—nor do they give you the ability to control anything that is not protected by copyright law, such as facts and ideas.

Creative Commons licenses attach to the work and authorize everyone who comes in contact with the work to use it consistent with the license. This means that if Bob has a copy of your Creative Commons-licensed work, Bob can give a copy to Carol and Carol will be authorized to use the work consistent with the Creative Commons license. You then have a license agreement separately with both Bob and Carol.

Creative Commons licenses are expressed in three different formats: the Commons Deed (human-readable code), the Legal Code (lawyer-readable code); and the metadata (machine readable code). You don’t need to sign anything to get a Creative Commons license—just select your license at our ‘Publish’ page.

One final thing you should understand about Creative Commons licenses is that they are all non-exclusive. This means that you can permit the general public to use your work under a Creative Commons license and then enter into a separate and different non-exclusive license with someone else, for example, in exchange for money.

Creative Commons is a non-profit organization with a mission to expand private rights to create public goods, creative works set free for certain uses.

Offering your work under a Creative Commons license does not mean giving up your copyright. It means offering some of your rights to any member of the public but only on certain conditions.

All of Creative Commons licenses require that you give attribution in the manner specified by the author or licensor.

Attribution Attribution. You let others copy, distribute, display, and perform your copyrighted work — and derivative works based upon it — but only if they give credit the way you request.

The core licensing suite will also let you mix and match conditions from the list of options below. There are a total of six Creative Commons licenses to choose from the core licensing suite.

Noncommercial Noncommercial. You let others copy, distribute, display, and perform your work — and derivative works based upon it — but for noncommercial purposes only

No Derivative Works No Derivative Works. You let others copy, distribute, display, and perform only verbatim copies of your work, not derivative works based upon it.

Share Alike Share Alike. You allow others to distribute derivative works only under a license identical to the license that governs your work.

Note: A license cannot feature both the Share Alike and No Derivative Works options. The Share Alike requirement applies only to derivative works.
Taking a License

When you've made your choices, you'll get the appropriate license expressed in three ways:

1. Commons Deed. A simple, plain-language summary of the license, complete with the relevant icons.
2. Legal Code. The fine print that you need to be sure the license will stand up in court.
3. Digital Code. A machine-readable translation of the license that helps search engines and other applications identify your work by its terms of use.

Using a License

If you chose a Creative Commons license, the small logo and license description will appear next to your deviation. It will link back to the Commons Deed, so that the world can be notified of the license terms. If you find that your license is being violated, you may have grounds to sue under copyright infringement. The machine-readable translation will be embeded in your deviation page.
