Scott Sims ~ ss396t6 just sent me this information regarding Part 2 and I googled it and found Part 1 also. Thanks, Scott for this information. Most of these are in our Advertising Forum already, but not all of them, and not with the additional information the articles provide. Though they go back to 2007, they still might provide you with good to know information.
