File talk:Unix history-simple1.png

Hello,

I think you used http://commons.wikimedia.org/wiki/Image:Unix_history-simple.png (There are the same Unixes, the same dates, the same links, the same separation of GNU (which is special), and you modified the page...), so you have to respect the licence:

Unix_history-simple.png is under Creative Commons Attribution 2.5 and you have to put the author's name.

Remember that the original author works probably hard to verify the informations and to sort them...

Thanks.

(Same problem at http://en.wikipedia.org/wiki/Image:Unix-history.svg)
