Hey Frank.
I tried to find some tutorials that may be helpful to you but didn't find much.
I did find this article showing some of the options available in the plugin.

If you scroll down to the Partial
Content Display description, then to the
Entire Blog Protection is that what you are trying to do?
I'm not being sarcastic or anything, just noticed you haven't gotten very far with this and figured I would try to flex my google muscles and try to find something helpful for you. It doesn't show you much but if those are the options you are looking for, at least you can see that it is possible to do it without modding anything.
Best of luck with it
