I offer my Sims 2 Stuff for use under what I like to think of as a casual creative commons license.
If you decide to clone, copy or redistribute my workmanship after making physical changes to the appearance of any part of the visual medium please take care to obtain a new GUID (where appropriate) and furthermore and much more importantly) to remove my catalog descriptions and to replace them with words of your own. The sweat I put into creations for Sims stuff is of little importance compared with the brain sweat I add to each every letter of every word I compose. I love my words every time a word of mine is raped by an uncaring muppet I dye a little voodoo doll rage red and sit on it, farting, for a whole day. Try imagine yourself under those circumstances ... it isn't nice, is it
I have come across one such case of numb-nuts "piracy" where a (not bad, because I chose to download it) wallpaper bore my inimitable Chintzy Lil dialogue in its catalogue description. Talk about being caught chocolate faced at the cookie jar!
I don't care if you edit the stuff to make it appear as if you made it yourself and upload it for sharing elsewhere. Charge for it you like. I'll hate you, but also admire your gall. But if you hotlink to my downloads (which, ironically enough, are hosted by the estimable HotlinkFiles.com (plug for my co-host - see how easy it is to spare the bandwidth!) I'll not only get cross and curse you I will also piss on your cornflakes.
