I think this blog (link below) by long-time networker Rafael Gonzalez (Spain) is hysterical, especially given the amount of add & passes that are circulating via IUOMA-Ning.
Personally, I've always believed it's impossible to f---- up an add & pass. They're foolproof. Like so much mailart the idea of "anyone can do it" underlies the genre.
But Rafael - who has been doing mail art a long time - is worried that he is messing up the add & pass.
It should give us all pause.... and a smile, I hope
