It is fairly common practice to do this ahead of actually issuing more shares, so a vote doesn't have to be called at an odd time when the decision to actually issue more shares is made. It can be done for a lot of reasons ... issue employee options, stock split.
Actually rachelelise, until I am corrected, I believe the recent PP w/warrants (and shares to pay interest) and the Globalwave shares bring total oustanding shares to 66M. Now there might be something else. If this is correct, it leaves 9M remaining of the existing 75M authorized.
