Re: Got that wrong then :-)
"Again, I am not talking about formal training or support here, which is clearly lacking in a lot of organisations, just someone who can say the words "try moving your mouse to the corners of the screen and see what pops up", and perhaps offer a couple of other basic UI tips."
Honestly, the majority of people out there don't have anyone to turn to, or if they do their help isn't much better.
For example I have a father in law who is pretty technically competent and never asked for advice, but when visiting him discovered that after using a computer for years when going on the internet he still waited for his ISPs home screen to load before typing in the web address he was going to into the search box on the page. That's what happened the first time he went online so he had been going online in the same way ever since. Changing the browser preferences so it opened with a blank screen confused the hell out of him, so much so that I had to set it to Googles home page so it was more familiar to him.
There are many others in the same situation, telling him something all of us here take for granted as common knowledge I would later find out he had used to impress his friends as their computer 'expert'.
