lightIRC is a free Flash IRC client that includes all well known IRC features.
It supports stylesheets for it’s own skins, has support for multiple languages, and can be used with every IRCd.
lightIRC supports channels, queries, a lot of IRC commands, some CTCP commands and is much customizable through StyleSheets. It has multi language support (currently English, Spanish, German, Turkish, Hungarian, Dutch, Swedish, Finnish, Serbian, Estonian, Romanian) and a nice GUI to set kicks, bans and channel modes.
The client uses a socket to connect directly to the IRC server (no XMLSocket, no gateway).
You need flash policy server running at IRCD’s host. Otherwise the lightIRC client can not connect to your IRCD. Here is a link of how to setup a socket policy server: http://www.adobe.com/devnet/flashplayer/articles/socket_policy_files.html
