Corel has been sending "The Painter's Canvas" updates since Painter IX came out.

Here are the links for the past several months. Each usually has 2-3 "how to" pretty decent articles on how to use a Painter IX feature or create an arty effect.

While many topics address Painter IX features, many apply to previous versions as well.
