It seems as though you need to do a couple of things BEFORE you can take part in his WEBCAST.
I (think) you have to Register. Then, I think you have to download some special software. If you DON'T do this BEFORE Wednesday, it will be 8pm by the time you get all set up. And if you really wanted to talk to Bob, you'd be very, very unhappy at this prospect.
I want to know if anyone is going to alert The Keiser about this. It would certainly be great entertainment!
