Pat,
I will definitely contact you for testing if I do another tutorial, I have one in mind and a first draft started, just have to get it all together.
I mentioned in an email to Marco that I used the bluefish editor to create the HTML, if that or another editor creates code that works, it would make the authoring process a lot easier (in case others wish to write as well).
I am fine with the licensing that Marco suggested and changed on my behalf, I will be happy to use which ever one is the current favorite.
About the images, I only use my own photos for editing examples & I will try to stick to inanimate objects & if I have to use a face it will be mine. I guess the only question about rights is if I capture a screenshot of a Gimp window or menu, I assume that I have the rights to that image as well. Do you know if that is true?
