I think that might be the usual use of NC -- to reserve commercial use or get yourself in on it. From Winfract's about box, "WinFract is copyrighted freeware, and may not be distributed for commercial purposes without written permission from the Stone Soup Group. Distribution of Winfract by BBS, network, and software distributors, etc. is encouraged." CC-BY-SA-NC I am not sure about SA, and I suspect that it is the case. The ND would have to be spelt out, researched, or guessed in a lot of cases. I said that I consider default parameters (and documented parameters) to be copyrighted, and that is idle speculation -- might not be the case. Some parameter sets are copyrighted. Some could do with a better colouring job. Formulas are all over the place, including tight holdings. _______ http://edmc.net/~brewhaha/Fractal_Gallery.HTM _______________________________________________ WikiEN-l mailing list WikiEN-l@lists.wikimedia.org To unsubscribe from this mailing list, visit: https://lists.wikimedia.org/mailman/listinfo/wikien-l
