The registration staement referred to in yesterday's filing was declared "effective" with the SEC on Sept.,2008. That means that all these shares were already"free trading" and can be sold at any time. The post effective amendment which was filed yesterday was filed to update it with current financial information,most notably the 10Q annual report which was filed last month.. By doing this, it keeps this registration statement current and therefore the shareholders can still sell if they want to. Don't forget, all of the shares in this registration statement were from the June 2008 private placement when the company raised $105 million at a price of $2.50 share.
