"The Great Drive Forward"?

Does anyone here participate on the Great Drive Forward forum or even heard of it? I got invited to participate on this forum through a survey company I regularly participate in after having completed a random survey on cars and the environment. Apparently it's invitation only but I haven't a clue if it's even worth joining.

 

I ended up joining by invitation, but it's basically a forum like this. The moderators will ask a question in the first post of a thread about various green car subjects, and then everyone else on the forum replies to the question as a post. There is some general discussion in there too, but not much. I haven't found any questions particularly worthwhile answering so I haven't participated nor even visited the forum. I'm not even sure who the moderators represent, so it's probably a pointless exercise.
