Miranda IM

Miranda IM used to be down as Miranda ICQ.

Miranda IM is a multi protocol instant messenger client. It works with as many protocols as their plug-in designers allow including ICQ, AIM, MSN, Jabber, IRC, Yahoo! and more.

The reason this program is popular is its size. The download is less than a megabyte and can be saved to a floppy disk or other small storage device. The program is small in file size and small in resource usage as well, while still providing all the basic features. Not to mention, it takes up the tiniest bit of space on the desktop.

A version without an installer is provided so you can run it from a storage device and possibly run it on systems where you do not have the permission to install anything.

Miranda IM is customizable. It can be skinned, including changes the text, icons, background, sounds and anything else to make it into your very own custom Instant Messenger. Many other messengers only let you change the sounds, background and text colors.

Miranda IM is yet another open source Messenger, which means you can expect hundreds more plug-ins created for it for any purpose. I would consider Miranda IM the small on the go messenger, but you can make this as permanent as you wish, and mold it into your very own.
