MultiChat is a chat client with the major focus on one-to-many communications (chat rooms and others). It does not aim to be a multi-protocol client. Instead, it seeks to provide multiple chat and collaboration resources based on integrated development with a single protocol and server software.
PTlink IRC Services provides channel/nick registration services for IRC networks. Specially developed for the PTlink IRC Server, it uses modules and includes features like channel roles, nick groups for privilege management, and a Web interface for users. The data backend is a MySQL database.
The PTlink IRC daemon integrates some of the most advanced features needed to manage an IRC network into the stable core from Hybrid IRCd. It is fully integrated with PTlink IRC Services and PTlink Open Proxy Monitor, providing a great platform for anyone starting an IRC network.
