This is somewhat off-topic and yet its related. Steve, you mentioned a link using the text "a little reading" in your article. On the website simpletalk.com, I believe. Well, as is the case with a great many useful websites, my employer blocks them. So, instead of "a little reading", for me its "no reading at all!!!!!!!!!!"

So would someone please be kind enough to give me a short synopsis as to what that link describes? I'd appreciate it.
