[JoeSmith]

TA = Transfer Agent
Share Structure:
OS: 177,350,630 - Float: 39,259,475 - Authorized: 490M (as of 01/29/09)
Transfer Agent: Standard Registrar & Transfer Co., Inc. 12528 S. 1840 East Draper, UT 84020 [phone]

All issued shares are counted in the OS, some are held by insiders, some are Private Placement (PP) shares, and the publically traded shares.
After 6 months PP shares can have the restrictive legend removed.
The TA does this, and adds the count to the Float, whether they are sold or not at that time.

Some great boards here in the investor edu section.
