We are in need of a module/page where we can configure all parameters for all our modules. Say, configuration for pricing, taxes, properties, etc.. We want this to reside on a particular module/page. We actually have an existing project/solution for this. I want to know how to add a new tab, just like the default admin and host tab and then restricting it to particular users. Or basically, I want to know how to integrate our existing project/solution to DNN. Maybe you could help me to figure this one out. This problem may be easy for some. I'm just very new with DNN that's why I'm having a hard time doing this rush task.

Thanks!
