As others have said, This board is in fact run off of a VBulletin Engine. The VBulliten engine is completly opensource, although you still have to register and pay a licensing fee.

The source of VBulletin is completly customizable php. The "look" of the board can be changed to virtually anything you can imagine with the use of cascading style sheets. So if your in the market for a board of this type, be sure you get some experienced PHP and css coders in your company. It would also be good to get some database people so that if the need arose, you could directly edit the database at the server level.


There are many free alternatives, although the only one I trust for security is phpbb. You can get the latest one at www.phpbb.com .
