One quick point. As there is no wide-spread abuse of images in sig, it would be foolhardy to start implementing new laws to regulate them. Me personally, if we are going to do this, I think it would be much better to do it before there is wide spread use of it. That way if the decision is made, it is much easier to enforce. I'd rather do it now, when we only have a few users to talk to, then in the future when we may have 50 to a hundred users to talk to.
