Currently, if you go under "Creo Modeling Questions" instead of "Additional Creo Questions", there is a label for Piping and Cabling. But if you want to post a question in Piping and Cabling, you have to Start a Question from within "Creo Modeling Questions", so that you can pick the Label "Piping and Cabling".
Need some clean up here by web managers.
Should also have "Start a question" available while you are in the Label. And that should be the default Label, when you start the question.
