New forum(s) for tools like TFS?

Is it possible to add a forum for “Scrum tools” with a sub forum for “TFS and Visual Studio”, or only one of these forums?

We are using TFS with the Scrum template and I’ve some questions. E.g. do we need “fix” and “test” tasks for every Bug item? When a bug is found for a PBI on the current sprint, do we need to add a bug item or a new task for the PBI, etc. etc.
