I think the introduction needs clarifying a little more. Some of the english could be improved. The large empty gap between the two bottom ads isn't that great because it makes the user scroll to see what's there, when there isn't anything there, and the right hand ad needs to be moved up the page a little. In fact personally I think there are a few too many ads. The page seems a little...I don't know, bland maybe. Some screenshots could be added of the product in use, as it might make more people want to sign up.
