The GNOME MUD client
GNOME-Mud is a Multi-User Dungeon (MUD) client for X. It supports aliases, triggers, multiple connections, command queuing, IPv6 servers and implements more advanced MUD protocols like MSP or ZMP. It includes a plugin interface, which can be used to add your own features (for example, a graphical health monitor). It uses the GTK+ toolkit, but it can be used with any window manager.
