I had an issue raised with me re use of copyright materials on Perplexus.
Some years back a discussion was held around that very subject. At that time I had no grounds to refute the decision made.
I'd appreciate some comment re the article at 10 Myths About Copyright and how they may apply to our usage of materials gleaned from sources not of the author's generation.
Please post general comments at Forums\General Discussion\Copyright but points specific to our usage here.
