I agree with Richard about cc-by-sa being the way to go with reference material. It is what I am using on the wiki reference wiki. http://inmysocks.tiddlyspot.com/#Copyleft%20Info
As a concrete example of why a more complex structure than a single license would be needed there is the interactive fiction engine I made. Tiddlywiki itself is BSD, the engine would be cc-by-sa and any content I made on it would be cc-by-sa-nc. I want people to be able to use the authoring tools to make a living if that is possible. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
