I know that active social will let me put an active social module on the page and specify the filtering of that module via the settings, but I really want to be able to have additional pages available automatically.

So far, I've created a razor script that list the categories available for a group and creates a URL to my Group List page passing c=CategoryId as a parameter (Using the NavigateURL() method in DNN)

What I need next is the ability for the Group List module to be able to pick that up and display only the Groups that are assigned to that Category.

Any ideas how I might do this without having to code it myself?
