On July 15th our old friend Chris Marquardt, the host of Tips From The Top Floor, will be taking the reigns at TWiT live while Leo is away in China.  Chris will host the TWiT Live feed all day and has an array of fascinating guests. A full run down of the Photo Day schedule is on Chris' site and I'm excited to say that I'll be one of his guests at 4pm PST - that's midnight UK time. Chris' other guests include Catherine Hall, Frederick Van Johnson. John Chiara, Jon Miller and Ron Pepper.

So please come along and watch as much of the day as you can and in particular I'd be over the moon if you joined me at 4pm PST to fly the flag on TWiT for PhotoWalkthrough!
