OK - it's official!  Dallas BarCamp 4 will be held somewhere in Dallas on September 29th, 2007.  I say somewhere, because we're not sure yet where we're going to be able to to hold it.  If you've got a location that might hold about 200 people during the course of the day and provide good, free, easy-to-access Wi-Fi, let me know and we'll get you involved!
