What is an MVP?

The Microsoft Most Valuable Professional (MVP) Program recognizes and thanks outstanding members of technical communities for their community participation and willingness to help others. The program celebrates the most active community members from around the world who provide invaluable online and offline expertise that enriches the community experience and makes a difference in technical communities featuring Microsoft products.
MVPs are credible, technology experts from around the world who inspire others to learn and grow through active technical community participation.
