Thought I would remind everyone of this post (in reply) regarding Form 144. If you buy restricted shares of stock (say via a private placement) you have to fill out a Form 144 in order to deposit the cert for those shares. Just because you file a Form 144 and deposit the shares does not mean you are going to sell the shares right away nor are you required to sell those shares within 90 days. But if you EVER want to sell them, you must actually deposit them somewhere first so you have them in a brokerage account and not sitting on you desk in a cert form. 

Some people intent on misleading unknowing investors continually tries to convince people that large shareholders are trying to sell or "dump" their shares. They are not. They simply want to have the shares in a form they can sell if they choose to. For instance if they were expecting the stock to rise in price in the very near future, they would probably want to go ahead and have them in a form they can sell. Whether they hold them or not, they would want to have them deposited somewhere. 

Anyone who tells you differently has another agenda and it is not to your benefit.
