You can buy them and reap the awards of getting the other stuff but only if you make the effort to move the shares to the protoshares wallet. If you keep them on the exchange, your awards will be given to the exchange and they seem to overwhelmed to bother dealing with passing them on to the rightful owners. I lost out on the memorycoin 2 because my shares were on bter, and they haven't responded to a couple of emails I sent.
