The point of the thread was if the restriction was valid or not...and it is. Whether or not you can enforce it is a moot point, because as the copyright holder you can. Whether or not people choose to honor your request is up to the person using it and boils down to being grateful that they received something for free in the first place and the respect to the copyright holder's wishes. Legally, yes you can do it. Practical? Not really...that is where respect and being grateful for it comes into play. That is what the thread is about. And I'm sorry, but if I've been given a present, like it or not, strings attached or not, I'm grateful for the actual present in the first place. A gift is not a gift if it's questioned. (oh this is great and nice but....) If I don't like the restrictions, I simply pass it by...there are already a plethora of columns. So yes, they can forbid you and enforce it if they choose to do so. It's called owning what you have created. Simple as that. And I'm not calling "everyone" ungrateful..but there are a few, you know it, I know it, everyone does..and they spoil it for the rest of us. Pendarian
