>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?

Using a table is a good approach for application settings. I am not sure I understand the question "What do I do for the BO?" Have you checked out the Dev Guid topic on Overview of MM.Net / Application Settings Classes ? I typically create a subclass of mmAppConfiguration for application level settings. With Web stuff however, I don't like to put stuff in the Web.Config and writing to files can be a question so using the database approach if a very good one.
