I think casamerica has raised and discussed some important points. However, what I think we are talking about are two different ideas, one is the copyright "rights" as legally defined, and the other is a "license" or grant of use which is defined most usually by contract. The readme files should be considered little contracts or license agreements, if you download the file and use it, the license or readme should be very specific. Since we are generally operating in rather new areas as far as enforcement and contracts arising between parties which are potentially in different states and countries, the forum of disputes becomes important to identify in my opinion within any license agreement. In short the copyright protections and contract or license for use become very important interactive "partners" in how we deal with the artwork and the use of other people's work. The forum is merely a place to put our work, so it is exceedingly important that the readme file become more specific as to what the artists' grant is for use. The reason I would mention this is because if the forum becomes involved too much they also become part of the "distribution" and potentially part of enforcement proceedings. Not that I am saying that the readme has to be 50 pages long, but a process of "I accept the terms" similar to the software packages would be what I am thinking is the high end notice...low end or more informal is the general readme. The issue I think in the most general terms then becomes a way of packaging the free use files so that the terms of the use are accepted in some demonstrable way. I agree we all must consider the "legal" terminology as is being pointed out by casamerica, commercial use has a specific Legal meaning we should become aware of, and in terms of the readme files we must begin to understand the grant of license and contract terms. For the most part we have many members who are new, they are not aware of the legal pitfalls. Posts like these are always relevant and on topic in my opinion.
