Apparently a site error
I thought I saw a mention of it elsewhere on the site, though on the relevant page would be helpful.
The site's most useful for knowing who and where to send things to, and for automating the process. You can still get a [link|http://www.junkbusters.com/cgi-bin/optout?from=eg&to=dma|template letter] and run the mods yourself.
To CRC and others -- back off, Norm was right on this, the form doesn't work.
To Norm: killing yourself over a busted webpage is, well, an inappropriate response (killing the programmer who wrote the page might be ever so slightly more healthy an impulse). If this is your default response to any event in life, you've got some very serious issues to address. Please do so soonest.
