We need to pick the list of categories for users to see - The Foreman team has done a great job with their discourse board (if we want some inspiration) - https://community.theforeman.org/
Here is an initial stab:
Release Announcements (?) - does this make sense for the way PatternFly releases?
Also - does differentiating between PatternFly 3 and PatternFly 3 in our categories just confuse things or should we encourage posting questions together and just specifying which version you are targeting?
