Thanks for the comments.
Off course a permission of any artist participating is an ABSOLUTE MUST. Also there is no transfer of ownership, however supplied the free item remains owner. The free item is presented as it is originally created by the owner and without any additional guarantee.
The idea would be to present free stuff on a CD and add a web to it. This then would allow to search based on categories, like "clothes for P4 women", "clothes for Vicky", "armor and weapons", "textures". That is the added value that is paid for (the work to collect and present the free stuff).
Finally, this is just an idea, nothing solid yet. Hope I did not upset anyone. This is just a thought of "Now you collected 1000 items, how will you organize the mess?"
