-          A smooth interface that enables you to ask, answer and vote on a question.

-          A free-form “tagging” system that allows you to attach your own keywords and phrases to your question to make it more discoverable by other users. With QnA, you tell us what the question is about, not the other way around!

-          Integration with Windows Live Spaces via modules that show off questions you’ve asked and questions you’ve answered.

-          See your score constantly increase on the Superstars page and earn reputation stars for consistently giving great answers.

-          Windows Live Messenger “gleams” that show when you and your buddies have participated in QnA.

-          Email notification that someone has answered your question, or when others have voted on a best answer, via MSN Alerts.

-          Ability to tag embarrassing or “adult” questions with the "mature content"  tag – which keeps explicit content away from those who don’t want it

-          Ability to subscribe to a customer, question or site search via RSS.

-         Message boards that let you get support information, discussions with other people, and contact with the QnA team.  You can’t chat or discuss things in Windows Live QnA without breaking the format… so instead, go to our message boards.  (http://boards.live.com/qnaboards/forum.aspx?ForumID=17)

-          You can always find news and updates to the service on this blog, http://liveqna.spaces.live.com!

 A few words to the wise:

 Carefully crafted questions get better answers. If people don’t understand you and your content isn’t adding value it will get reported and taken down by moderators. Try to respect the grammarians and the need for proper spelling so that other searchers can find your question!  We know you want a spellchecker and we are working on this, but please bear with us in the meantime.

 QnA is still supported only for English at this time. We ask our international friends to be patient with us as we explore opportunities to make QnA available in other languages. At this time we are English-only, but as you see us roll out other languages you will see versions of the Code of Conduct in those languages.

 The best tags for a question are a combination of broad and specific. For example, a question about making scones should include “Food” (broad), but also if you want particular answers or people to find it, you may choose to add a more specific tag like “Baking” or “Whole Wheat” so others can find you and give you their best recipes.

 Use the QnA search box to find questions on topics that interest you. Questions vanish from the home page in an instant, and the best ones for you to show your expertise may be buried quickly. You can subscribe to a search for specific topics via RSS for questions related to your expertise.

 Have fun, challenge yourself, be respectful…..
