if their contact info on their site is no good, then drop them like a bad habit.
I always email before I signup to a program and ask a few questions. it's why I don't promote 1/2 of the prog's here. if they can't answer normal questions, then they will flake if/when they fuck up... so why even bother.
p.s. I was taught to do this years ago and have never gotten ripped off.
