I always find it funny when the help desk people whether they are web help desk people or a help desk located in a building are not friendly people! And it almost seems they are bothered by you asking for help.
It makes me wonder what qualifications the help desk job requires.
I have had many good experiences with online help desks, the kind that pop up when you enter a site and the window says "So and so is here to assist you, please type in your question or comment."
I just type in what I am looking for and that person answers my question or leads me to the information. I feel the help desk online has saved me an abundance of time searching for a specific answer!
