This user does not wish to speak or hear dumbass, but is resigned to the necessity of at least understanding it in an environment of massive collaboration.
When a project includes multiple operational pages, it is generally best to redirect their discussion pages to the main discussion page for the project. That way, participants remain aware of what is going on with the project without having to search out every nook and cranny where discussions may be taking place.
The exception to this strategy is when a task is delegated that would generate a great deal of discussion, and centralizing it with the project's other discussions would create a discussion page of unmanageable size.
