Using Instant Messaging is one of the fastest ways to communicate with someone over the internet. With all th edifferent instant messaging clients out there, almost none compares to meebo.
Meebo is an instant messaging software that runs inside a Web browser, as AIM Express, which supports multiple IM services, including Yahoo! Messenger, Windows Live Messenger, AIM, ICQ, Jabber and Google Talk. Meebo makes instant messaging services more accessible to users who are unable or unwilling to download the software necessary to implement them.
Another great thing about this is that it has options for video cam and file transfers. However, it’s not yet a 100% as its still being tested. In the meantime, it’s one of the best IMs out there, so try it out!
