There are a lot of Yahoo Messenger users who own more than one account, although it's somewhat difficult to understand why would you ever use more than one identity when chatting on the Internet. Whatever the reason is, Yahoo allows only one instance of its Messenger to be ran at a time, but a life-saving solution comes from Y! Multi Messenger.Just like its name suggests, this little tool allows users to run multiple instances of Yahoo Messenger, and thus chat online with more than a single ID.It can't get easier than this: Y! Multi Messenger is a tiny executable file whose setup takes only a few seconds. The only thing we had to do was to write down the folder that hosts Yahoo Messenger's files, with the setup wizard doing the whole magic in just a few moments.The interface, if it could be really named so, is a simple screen that allows us to enable or disable the patch which allows the running of multiple Yahoo Messenger instances. Plus, a bonus: tired of the advertisement banners displayed at the bottom of the main window? Y! Multi Messenger can remove them too. Don't worry, if you're an avid advertisement fan, you can bring them back using the “Reinstate Ads” button.And that's basically it. A simple program with a simple interface that does a simple thing. It couldn't be any simpler than that. What we liked the most? Probably the idea behind the program, although sometimes we don't really understand what's with all this instant messaging frenzy that's going on these days.
