Actually there have been successful attempts to legally force people to remove wb/ks rom images from peoples sites. Personally I think youre potentially asking for trouble keeping them there, especially in light of you drawing attention to yourself. I dont really care myself, but I'd be surprised if it wasnt just a matter of time before you received genuine emails over it. As for OS4.x, it's the amiga based OS I have least interest in, but to call it crap just 'cos it doesnt run well on an old bppc+aga combo is a bit far fetched.
