Hey DKoor- true PHPbb, and SMF for that matter are forums with lots of varieties. Corporate culture often dictates a uniform look and feel to provide a cohesive, consistent message that is as identifiable with that corporation. As having done some contracts with corporate communications departments, I know first hand that some have what is known (unofficially) as "Branding Police" who enforce the company's look and feel, as well as educate staff designers and art directors as to what is acceptable and what is not.
