Ayttm is an instant messenger program, supporting various protocols such as MSN, Yahoo, AIM, Jabber, and more. It is a fork of Everybuddy, and initially aims to address its problems. It should not segfault when you use it, and should be almost instantly usable by your mother. Almost useless prefs should be hidden, reserved for "advanced" users, and things have to work without wondering what this or that will produce.
Supybot is a clearly-written Python IRC framework and bot, intended to be both easily extensible and very flexible. Several modules are included by default. Numerous plugins are already written, including Google, Factoids, RSS, Quotes, and Relay. Plugins and their commands achieve greater utility via command nesting, something that no other IRC bot does. The user database is based on "capabilities" rather than obscure flags or arbitrary numeric "userlevels", giving the bot flexibility and fine-grained control (think ACLs vs. standard *nix permissions). Developing your own additions to the bot is simple with the base classes provided; writing a new command for the bot is as simple as writing a function. Unlike many other IRC frameworks, this simplicity is achieved at no cost to generality, which lets new programmers and old programmers alike feel at home in the framework.
JForum is complete, powerful, database-independent, and multi-threaded forum software. Features include unlimited forums and categories, topic watching, email notification, private messages, user ranking, an advanced permission schema, and moderation options. It provides support for many languages and customizable templates per user.
The Bahamut IRCD is based on the EFNet Hybrid IRCD and has many additional features primarily designed for the DALnet IRC network.

Bahamut is not compatible with Dreamforge as of version 1.2.0.
OpenIM is a Java implementation of a Jabber server. It is a complete rewrite of the Jaba Server project, and it supports the Jabber server to server communication protocol. It also supports Presence, Message, and Roster. Persistent storage is done in an XML file using XStream lib. It has been tested successfully with many clients such as Exodus, Rhymbox, GAIM, Psi, Greenthumb, and the Kopete.
dircproxy is an IRC proxy server ("bouncer") designed for people who use IRC from lots of different workstations or clients, but wish to remain connected and see what they missed while they were away. You connect to IRC through dircproxy, and it keeps you connected to the server, even after you detach your client from it. While you're detached, it logs channel and private messages as well as important events, and when you reattach it'll download those logs to you using ordinary IRC protocol.
Beonex Communicator is Mozilla polished for end users. It contains Navigator, Mailnews, Composer, and ChatZilla. Navigator has support for key web standards and a convenient interface. For example, it eases searching the Internet, similar to Apple's Sherlock on Macintosh. The Bookmark Manager can deal with huge collections of bookmarks and allows you to overview and sort them while you are surfing. If you want, you can track the latest headlines or webcams using the Sidebar. The Mailnews client supports multiple IMAP, POP3 and/or news accounts for each user, so you can download and manage all your email from various accounts in one place and store them on your computer or the server. Beonex puts a strong emphasis on security, privacy, and netiquette, to protect the private or confidential information on your computer and to encourage fairness.
