I'm having some trouble finding it. I searched the site pretty thoroughly and am unable to locate the article you referred to.
Here's how to post a web link for the newbs amongst us.
When you are on the page you want to copy, look in the address bar above the page. Click anywhere in that box so that the entire address is highlighted. Press ctrl-C (the control key and the C key at the same time) to copy it. Now come back here, and press ctrl-V to paste the address.
