Peng. This is really, really, poor taste man. On that blathering web site it says you teach Network Administration. So if I were to treat you the way you are treating merchants. I guess what I'd have to do is sit in on one of your classes. Take notes. Then come here and rave about all the mistakes you made teaching your classes. There's no difference. If people want to buy things that aren't perfect. That's their business. As long as the problems aren't hidden from view it's not your place to crusade against them. If your faculty and students allow you to teach Network Administration by spending little or no time on IP protocols and more time on Network security procedures. Just making this up as an example. It's not my place to go to a public web site and crusade against your teaching abilities. I know you're just trying to help the community in general. But man you gotta see how it looks from out here. It came out looking really ugly and hostile. What goes around comes around. My advice is to duck. ;-) -ScottA
