Yes, I do already have the property defined in both JdaBusinessWebPage and JdaBaseUserLogin classes. I also have all of the logic to build the base path in the OnLoad of both of those classes. Having that exact same code replicated in multiple classes stinks too, but I have some pages based on Kevin's mmBaseUserLogin class and some pages based on his mmBusinessWebPage on my site, but they all need this property. I don't see any way around replicating that code. :(

I do understand what you were saying about defining the Interface so I can cast to. I will probably go with that solution for now. Thanks!
