I just came across this article and found it very interesting. I agree with it. I think its very important that a church has a good strong identity. If it is promoting a event and the promotionaly material is strong and up to date it will amke it seem much more credible and relevant. After all it is all about preading the gospel and making it accessible to people, if good design and a strong identity can improve this aspect then people should embrace it and try and use it.
