It means you release you release your work under a homebrew license consisting of: "I, , the copyright holder of this work, hereby irrevocably grant anyone the right to use this work for any purpose, as long as they credit me and share derivative work under the same terms." This has a number of problems: 1)It doesn't clearly allow for derivative works 2)Poor handling of the derivative works issues complicates the who to credit issue with regards to derivative works 3)no equiv of "a later version of this License" which given the above problems and that CC-BY-SA 3.0 itself contains a typo is a bad thing 4)No equiv of "For the avoidance of doubt, where the Work is a musical work, performance or phonogram, the synchronization of the Work in timed-relation with a moving image ("synching") will be considered an Adaptation for the purpose of this License." There are other issues but I hope you get the point. Homebrew licenses are a BAD THING. Additionally the people who wrote CC-BY-SA know far more about copyright than you thus it's best not to fiddle. Lack of links out to the license is also a problem. "a Creative Commons Attribution ShareAlike license" is also imprecise as it means any one of 3 separate licenses (and thats before we consider people saying things like "version 1.0 only". On a separate point taking out the traps tempting as it is is a bad idea. Remember most people think we are like youtube who only pretend to care about copyright. The traps are one of a number of weapons we use to deal with that. Technical: Your video thumbnailing is broken. System locks up when you try and upload a duplicate and won't let you go backwards. -- geni _______________________________________________ Commons-l mailing list Commons-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/commons-l
