Thanks for the clarifications, Jesse. I'm going to pull Mark into this conversation to see how he might want to handle the openjpa-maven-plugin documentation request (since he's the author of this plugin). We should be able to do something to make this more prominent. Thanks for the input. Kevi

Hi Jesse, Can you further explain which openjpa-maven-plugin "site" you are referring to? On our maven enhancement page [1], we have a reference to this site documentation currently hosted by mikedd: http://people.apache.org/~mikedd/openjpa/openjpa-maven-plugin/ Is that what you referring to? Or
