I like the program that they run, and I like webgurl that works for them.. but they never converted for me. I went 0:3000 before i switched sponsors. I was only pushing the $1 trials too.
It was mostly TGP traffic... with some free site traffic mixed in there.
I have this feeling that people think the $1 trials are a scam or something. *shrug* who knows. But that was my experience.
