"Maybe it would be a good idea to include a basic tutorial on how to use internet search engines in the tutorial page,it would certainly cut down on the 'I have searched and searched and cannot find anything about resistors' type of question."

It's totally pointless, they wouldn't be able to find it let alone read it. And anyway, I don't think the problem is usually caused by an inability to use search engines. On the occasions that I've taken a look on Google for something one of these people have allegedly searched for I just stick one word in the search box and up come plenty of useful links on the first page. Nothing complicated required! It's clear that they haven't actually searched at all.

"I have searched and can't find..."
