Imo is a website that lets you message with your friends and colleagues from right inside your browser.
It supports all the main Instant Messenging clients, such as MSN, Skype, Yahoo, GTalk, AIM and Facebook, to name but a few.
This is worth checking out if you’d rather not download and install multiple Instant Messenger clients, instead having it all from within a webpage with no software to download.
Imo is also available for Android,Blackberry and Nokia , where you can also make VoIP phonecalls on some devices.
