In calling this to the general attention, I was indeed fully aware of 
the different problems involved. They are not easy to solve I guess. 
Licensing is tricky. Many goodies were just brought to us out of 
courtesy without - I suppose - any idea of restricting their use within 
the limits of what is fair and proper like mentioning original author 
and subsequent changes, and/or a known use history, and some form of 
self-imposed use restriction. Still, there is an immense variety of 
things going from snippets of code to complete scenes and that is 
difficult to manage properly.

I am no expert on this but if knowledgeable people could assess the 
potentialities of wikimedia or github, I and many here would certainly 
be most grateful indeed.
