Bing, many know is a Search Engine in which is powered by Microsoft. They are trying to get the word out of their toolbar by giving out free Microsoft points! They will send it to you in the mail, but then again...you can't beat free! The link to download the new Bing Toolbar is here: http://www.discoverbing.com/toolbar/
You actually get 250 points for the initial Toolbar Download, which 100 Microsoft points cost 100 Bing Points. So, that will give you a good 200 points. You also get points for doing searches using their Search Feature, and can add up quickly if you think about it. Google is the old, Bing is the new!
