HI, The redesigned Bing Webmaster Tools provide you a simplified, more intuitive experience focused on three key areas: crawl, index and traffic. New features, such as Index Explorer and Submit URLs, provide a more comprehensive view as well as better control over how Bing crawls and indexes your sites. Index Explorer gives you unprecedented access to browse through the Bing index in order to verify which of your directories and pages have been included. Submit URLs gives you the ability to signal which URLs Bing should add to the index.
Its a Good update from bing. I hope bing will give you more update like this. FYI bing has introduced access with out install silver light api. Hope bing will survive good about its update
Before some weeks i heard a news about bing webmaster tool that yahoo is going to shut down its service "yahoo site explorer" and will redirect it on bing webmaster tool, therefor i think bing webmaster tool has update its features.
Whatever it maybe, either way Bing doesn't seem to take action as fast as Google does, thus falling apart in competition.
