>I need to let the user define some values which will be made use of by the Business Object code. I have a Settings file and class that work for a config file in my web/UI, but what do I do for the BO? Do I use the app.config file? Do I create my own My.config? Or should I use a table to store the values and create a BO that accesses this table?

Either way will work. I'd say the extra config file with settings or table with settings sound like a good idea.
