Meebo (All in one Web based IM)
When I was working for a company couple of years back, I found this wonderful website for chatting without downloading the chat software.
You may not have permission to download and install any software in your office PC. But if you want to chat with your friends and family members you do not need to install any software in your system.
Meebo is the choice for everyone.
Meebo Supports, Yahoo Messenger, MSN / Windows Live Messenger, AOL (AIM), ICQ, Jabbar, Gtalk (Google Talk)
Meebo also supports Playing games, video conference, transfer files, and so much more, all from your Web browser.
It normally works with popular browsers like Internet Explorer, Firefox and Opera.
Some times if you have any restriction on your computer using firewall, you may not be able to chat. You can also find the work around in Meebo Instant messaging website Meebo.com.
