Yeah, I'm confused too but i think as more people participate/the market opens up it will start to become more clear. I just hope it becomes clear before i lose all of my money.
for those of you that haven't cound it it's under 'The Site' way over to the right in blue. check it out.
And for NoPoles, I hope people don't do this but im guessing some shitheads are planning on making aliases just to try out different stock buying options... sooo i suggest you make the SSE a privelage that you can only earn after you've been a member for six months or something along those lines. Thanks!
