Gnutella2 Developer Network

Welcome to the Gnutella2 Developer Network. The Gnutella2 Developer Network (or G2DN) is a convenient central location for discussing, developing and documenting all aspects of Gnutella2. Like the Gnutella2 platform itself, this website is designed to evolve through community support and participation. Everyone is free to contribute discussion, proposal documents, developer resources or any other relevant material.

Although the G2DN is primarily geared toward developers and technical enthusiasts, users of Gnutella2-enabled software are also welcome to participate. Those who are new to Gnutella2 may wish to check out some of the Gnutella2-powered software.

Feel free to contribute to the wiki after reading Gnutella2:Community Portal to learn about editing policy.
