One other time i needed jumper info, it only took 3 days of emailing back and forth to get the sheets. After asking why it's not on thier site i was told "it's not something we want the customer to mess with." Anyone familiar with the legal ramifications of having a site up that has anti-testimonials about companies, I have quite a few on my sh*tlist and email corrispondance with these companies to show why. I'm quite sure stuff like that falls under "fair use" no?
