Love it

If you use more than one instant messenger, this is a must have. You can go to there site and use it via browser, or use the app from a mobile device and log in to all your messengers at once. Saves time, and a lot of memory.

I recently found this online messenger. It has been very helpful when it comes to making voice calls to MSN, Yahoo, and Skype on Linux (Ubuntu).
