15 December 2009 UTC Thank you for your note Yes you certainly can write about the same subject The problem with the rewrite you propose is that it still has the structure of the original which makes it still a derivative of their work even though you are replacing some of the words with synonyms I do a lot with rewriting to avoid copyright problems and I know it can be a pain in the neck to find completely new ways to say something Give me a minute to draft an example and I ll see if I can help you 17 14
