Hi, Sometimes I take part in conferences. I completely agree with you that some of them are boring. In this case, it doesn't make sense to enroll to another boring meeting. But in my life I have participated in many interesting conferences that I could learn something useful and meet very clever people. We exchanged with our knowledge or experiences. I also agree that some basic things are extremely important. I mean: proper temperature in the meeting room, proper light, tasty lunch, comfortable hotel room. We can say that all of this make us happy and more productive. Ofcourse this is only my point of view. Greg
