No registration required! (Why?) (any good?)

Hi all, found a site thru a freind (who swears by it).

It is a kind of virtual (but not) stock simulation (but not) now its
the only one I know of that offers a real cash prize every 30 days.
Anybody have any experience with this kind of thing? It looks quite
good, but would love some feedback from people who play these types of
realworld game. The jackpot $12K goes in 8 days, what ya think about this route into trading for a beginner?
