Konversation
Konversation is an Internet Relay Chat (IRC) client built on the KDE Platform and is free software released under the terms of the GNU General Public License. Konversation is currently maintained in the KDE Extragear Network module, which means that it has its own release cycle which is independent from the main KDE applications. It is the default IRC client in many prominent Linux distributions, such as openSUSE, the KDE spin of Fedora, and Kubuntu.
