Features and Highlights
A friendly face for everyone
Whether you use Windows, Linux, or a Mac, this tool is right at home on your desktop. From the system tray icon on Windows to the dock badges on Mac OS X, the app takes advantage of each operating system's unique features and appearance to provide a first-class IM experience on almost any computer.
And since the software is designed to be fast and lightweight from the ground up, you're free to enjoy all of its features without slowing down the rest of your system.
International citizen
Thanks to the efforts of volunteers around the world, localized versions of the tool are available in almost twenty different languages. And with its built-in support for the Unicode international text standard, the app can also send and receive messages in virtually any language. Casually converse with accents, symbols, and right-to-left text — the tool won't miss a single stroke.
Have it your way
The software's appearance is highly customizable, so you can choose the colors, icons, and emoticons that suit you best. With many user-contributed iconsets to choose from in the community, you're sure to find a look that matches your mood and personality.
Flexibility should be more than just skin deep, of course. That's why the tool lets you tailor the interface to your liking — customize toolbars, keyboard shortcuts, and other options so you can chat just the way you like it.
Always-on security
Using the same SSL technology that makes it possible for you to safely shop on the web, the program automatically encrypts its communication with compatible IM servers to provide a secure connection over untrusted networks like public WiFi access points. For advanced security needs, the tool can also encrypt messages end-to-end with OpenPGP.
Leading the way
The tool's developers are actively involved in the Jabber community, working hard to ensure that the software fully supports the standards for features like avatars, multi-user chats (with full admin control), remote client control, and more. It's standards like these that allow people to communicate smoothly with each other on the Jabber network, and the app ensures that you'll never miss a beat.
