`  :You may find that when you follow the procedure I prescribed that the category doesn't properly update. This is a flaw in the Mediawiki software that Wikipedia uses. To ``refresh`` the category you need to null edit each of the pages that should be appearing in the category. You can do that by opening the edit window on each of the pages and saving (no need to change the page). You don't need to do this, the next time each of the userpages is edited it will be ``refeshed`` and will appear in the category - I'm letting you know why things was appear strange. `
