Here is a post about Mars Hill Church in Seattle and their demand that another church change the name that they share. The irony is not so slight.
Also included is a public notice from another congregation, Watermark, who politely warns others against copyright infringement.
On a somewhat similar note, Notre Dame University is demanding that the high school in Chapman, KS (pop. 1300) stop infringing on their rights as well. I guess Chapman HS merchandise was flying off the shelves. The video shows the people of Chapman responding with class.
