Last month, I got an email from Matt Vance who told me that he used some of my Hawaii photos in a Wiki presentation that he put together. This is all legal and legit because my photo gallery is licensed with the Attribution, Non-Commercial Creative Commons license. This is a shining example of how this license is supposed to work in the real.
BTW, the use of Hawaiian photos for a Wiki presentation is very apropos since it is the Hawaiian word for "quick".
