No the reason I am doing this is because I use the plugin Dyanic Widget. It is much easier to set up widgets when there is a parent/child relationship. I can just set it up so that it shows on every page that has a certain parent and just forget about it. Otherwise I need to go page by page.
Is there no way at all? I am sure there is a way to do this to remove the catergory from the permalink as I have used this in the past. But never tried for the parent/child pages.
