No. For privacy reasons everything is handled within the forums. Email addresses and phone numbers posted are redacted almost as soon as they appear.
The other reason that we end users work within this open setting is that a question that User A posts can indirectly help Users B to Z who came here with a similar need. That is "community" at work. Help others.
You may find third-party Apple user sites that allow private messaging or other contact outside the forum confines, but Apple have not provided that feature here, again, largely for privacy and security concerns, as well as building the general knowledge base.
