I think a way to make everyone feel secure is if the contributor posts how large their "READ ME" file is in the fun pages. That way, if I see a texture map that weighs in at a meg and a half, and the "READ ME" file is 300k, I can be informed that it is probably something I don't want to waste my time downloading. Seriously, think twice about whether you really want to make a prop or texture available online. If you feel you're going to freak out if you see your creation somewhere you didn't expect to see it (i.e. the Adult gallery, someone's portfolio, etc.) then maybe you're doing yourself, and everyone else a favor by not uploading it. I can understand retaining some rights, and wanting credit for something you created, but if you're going to give it away in a general forum, don't bog it down with a bunch of restrictions that you can't possibly enforce--let it go. There have been some things that I've posted on the Fun stuff and Free stuff pages (someone actually asked for permission to use one of my items--I was so stunned that I actually recreated the prop, made it better, and added a whole bunch of morph targets to it before I sent it to her--I also made it a point to send her future props before they made it on the Free Stuff pages), other items I send via email, and items like characters (which I seem to get attached to in the process of creating them) are kept securely on my hard drive.
