In the case of that example, you should probably add ".net" after the "WNFF", perhaps in a smaller font (matter of taste). I am also of the opinion that if you're trying to advertise something, it should always go on the back of a shirt, not the front. After all, who's going to stare at your chest long enough to read something?
I have no problems with someone else doing a design... I just wanted to get a mock up for others to see what we could do.
Truth be told, I'd rather you just set up a WNFF paypal account so we can donate money to the site.
