Chairman Leonard Riggio, B&N's biggest shareholder, says he may join with a group that will bid for the company. In June the chain forecast a possible loss of 40 cents a share for the current fiscal year due to a $140 million investment in its digital book unit.Research in Motion: Too Secure for Saudi SnoopsSaudi Arabia has ordered the suspension of BlackBerry's instant-message service because officials can't monitor the traffic on RIM's (RIMM) encrypted network.
