X-xChat is another great Free Portable IRC Chat Client offered by winPenPack. X-xChat is essentially based on the unofficial XChat with a portable wrapper. Aside from being portable, X-xChat offers two additional features not found in most other IRC Chat Clients; colored nicknames and alignment by text as opposed to alignment by nicks. These features are carried down by X-Chat.
