The Evolution of Pranking Goofery into Some Kind of Cyber-Performance Art Type Thing. I've been screwing with business-reply mail for quite some time, having returned several thousand blank/defaced cards & envelopes over the years. It's fun, but at the same time, even if anyone in the mail room notices my messages, they have no way to get a message back to me. Recently, I wondered what would happen if I invited people to respond to their reciept of the things I've been returning. So, I ordered 500 stickers with special instructions printed on them- (Yes, I know the stickers are hideous. They were on SALE, and I'm frugal with my 'art'). The URL eventually directs respondents here.
