rtfm has been a long time mantra in the IT community.
I long ago decided that if anyone actually did...... I'd probably be out of a job.
A lot of this crap is easy.
I just had a guy call me to say that his browser was stuck it full screen mode and wanted to get out of it. When I told him to hit F11, he was convinced that I was Einstein
Probably would have taken him only a minute longer to find the same help in the browser that was already open on his computer.
Nobody wants to search for or read about solutions, they want them handed down from on high. Hence..... why I could afford to retire at age 55.
