People will be able to search the MHM database using the categories presented to you when you register. They will also be able to cross-reference those choices with language abilities, MVP or Microsoft Certified Partner status, and by geographic location. If you are an MSDN Regional Director, MVP, or Microsoft Certified Professional, your record will be highlighted in the search results. Those with questions will submit their issues or questions using the MHM submission form. The e-mail message will be sent to both you and the requester with the question, contact information for both, and several links to helpful resources.
Most people answer questions through e-mail.
You can also reply by phone or fax if those numbers were made available. Once you've answered an MHM question, you might want to share this answer with a wider audience. Responses chosen for publication in the Peer Journal will be archived for others to see and use. This is a great way to make your answer public and permanent, and could save you time. If a similar question comes up in the future, you'll be able to simply point to the MSDN Peer Journal for the answer.
