You can easily take an RPN logo and slap it on some Tshirt designer website somewhere. Some arent that expensive to make.

@The Dark Wizard Hey man, this guy wants a shirt. I suggested just making his own for the time being, as you do not have a store for shirts yet. Could he possibly make his own design for himself and not sell it? I understand copyright and all.

I'll have to find out. The reason why I haven't setup a store yet (I really want mugs, I'm a crazy mug guy) is because of trademarks and other stuff we are busy doing.
