Hi friends, we all are using web browsers for logging-in to Orkut . but there is a portable Orkut messenger software. The name of the software is Orkut ScrapBoy. Using this software you can do everything related to orkut from your desktop itself. It is like Yahoo messenger. just check(tick) the check box @ Remember me. Check out the screenshots given below
Another good thing is that you can sign in to your Facebook and Myspace accounts along with Orkut at the same time. You can easily switch to one another without signing out from any of these social networking sites. Simply access your Orkut, Myspace, Facebook account at a time from one messenger. Could you imagine anything easier than this?
