I think what they're doing with the form is called shelf registration and this latest S-3 is just an amendment to the document filed a month ago. "Shelf registration is a registration of a new issue that can be prepared up to three years in advance, so that the issue can be offered quickly as soon as funds are needed or market conditions are favorable."
So it looks like they're getting their ducks in a row right now to raise up to 8 million at some point in the future.
This part of the S-3 was fascinating...
"As of June 1, 2015, we had outstanding 6,032,222 shares of common stock, held of record by approximately 172 stockholders, and no shares of preferred stock."
How is that even possible?
