Earnings Per Share [Abstract] |
Net Income (loss) Per Share | Net Income (loss) Per Share Basic net income (loss) per common share is computed using the weighted-average number of common shares outstanding during the period. Diluted net loss per common share is computed using the weighted-average number of common and dilutive common equivalent shares from stock options, warrants and convertible debt using the treasury stock method. For all periods presented, diluted net loss per share is the same as basic net loss per share, as the inclusion of equivalent shares from outstanding common stock options, warrants and convertible debt would be anti-dilutive. The following table sets forth the computation of basic and diluted net loss per share:
| Three months ended June 30, |  | Six months ended June 30,
| 2013 |  | 2012 |  | 2013 |  | 2012
Net income (loss) | $ | (757,389 | ) |  | $ | (744,069 | ) |  | $ | (2,377,797 | ) |  | $ | (1,837,721 | )

Income (loss) per common share - basic and diluted | $ | (0.01 | ) |  | $ | (0.01 | ) |  | $ | (0.03 | ) |  | $ | (0.02 | )
(a) Securities outstanding that were excluded from the computation, prior to the use of the treasury stock method, because they would have been anti-dilutive are as follows:

| 2013 |  | 2012
