I am almost finished the first go at ey143's hack (I need it, too), and will look at PHPNuke when I install it (the next thing on my list!).

I am a big fan of common user info. One big supplier whose name shall remain unmentioned has had two separate, system assigned user name and password combinations for three years (they are different and cannot be changed), and their login screen has said, that whole time, "We are working on having one login..." Give me a break!
