The premise is simple. Answer a question a day, which I assume goes to research firms, etc, but you get points for every day your log in and answer questions. It's invite only right now, and it takes a while to rake points, but the rewards are pretty cool.
Anyways, I have a membership and am willing to send out as many invites as I can to TFPers, who can then in turn mail them out to other TFPers. If you're interested, pm me your email. In turn, those who have the ability to send out invites and are feeling generous, post here so other's can get invited too.
You have nothing to lose, it seems. Except your soul to marketers
Edit: I just realized that I'm not too sure if this is the proper forum to place this. I just figured electronics, but it seems the posts here are more technical.
