Microsoft SearchTogether is a free Internet Explorer plug-in that allows groups of people to collaborate on Web searches.
To use SearchTogether, you will need to have a Windows Live ID. SearchTogether runs in the Internet Explorer 7 browser; you can click here to download IE7. If you want to invite your friends to join you in a SearchTogether session, you will need to add them to your buddy list in Live Messenger.
SearchTogether can benefit any group of people who are interested in investigating a topic together, such as students working on a group report, colleagues working on a joint project, or friends planning a shared vacation or other social activities. SearchTogether supports both synchronous and asynchronous collaboration styles.
