Exactly, one should be careful when dealing with teachers as customers. Don't mean to generalize but the school teachers are not known to be internet/computer savvy. Especially the older and slightly older ones who didn't use internet in their teens. After dealing with rowdy kids, they are just too pooped to sit in front of a computer to learn something new. And I don't mean to put them down. Being older and not having the energy after a challenging day at work are serious obstacles to overcome to learn something new...

I know. My wife is one.

Btw, a doctor friend told me he knew of an older doctor who simply retired because he didn't want to be forced to learn to use the new electronic charts. So learning internet/computer is a challenge even for well educated people also...
