Line of Credit [Abstract]
Line of Credit	10. Line of Credit On February 11, 2009, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Silicon Valley Bank (“SVB”). The Loan Agreement was renewed on February 8, 2010 and again on February 9, 2011 and matures, on February 9, 2012, at which time, any outstanding principal balance is payable in full. On August 3, 2011 we received a letter from SVB indicating that the Company’s failure to meet the minimum quick ratio of 1.25 to 1.00 for each of the periods ended February 28, 2011, March 31, 2011, April 30, 201l, May 31, 2011 and June 30, 2011 constituted an event of default. As of the date of this filing, the Company remains in default of the quick ratio financial covenant. We currently have no borrowings outstanding under the Loan Agreement and the Company’s future ability to borrow under the Loan Agreement may continue to be suspended based upon our failure to comply with the quick ratio covenant in the future. The Company is currently seeking other forms of financing, however, we cannot be certain we will be able to secure additional financing on terms acceptable to us, or at all.
