I have no encouragement to sign up. Why not? Because I can't see what kind of discussion is happening in the community. If I click on any of the communities I get a sign up pop up and no discussion. I'm not handing over my info till I see what kind of discussion is happening. I get frustrated and then I'm off to Motley Fooll CAPS or Stockhouse.
