 == Conclusion ==
 [[NetHack]] is a '''free''' game; the rights granted in the NetHack GPL have caused several important effects among the NetHack community. The fact that NetHack is easy to obtain, and that there are many [[variant]]s and [[patch]]es, and that [[spoiler]]s are possible, relies on the permissions in the NetHack GPL.

 The most important consequence of copyleft may be that commercial game vendors cannot borrow NetHack source code for a game unless they make their game into a free game.

 For NetHack to become a successful and popular game, there would have be a way for the people who had NetHack to give it to the people who missed it. The NetHack GPL was the document that provided the permission. Because of this permission, some FTP sites also started providing archives of NetHack, so that more people would become able to obtain it.
-Today, the [[DevTeam]] uses [[wikipedia:SourceForge|SourceForge]] to host their web site and to distribute the game. SourceForge provides NetHack over many mirrors. (They are careful to maintain each [[mirror]], because for each one they break, they lose 2 [[luck]], assuming that these mirrors obey NetHack rules. Fortunately, the numerous mirrors scare hostile [[monster]]s away from SourceForge.) It is very easy for anyone with an internet connection to download NetHack from SourceForge.
+As of June 2024, the [[DevTeam]] uses [https://www.nethack.org nethack.org] and [https://github.com/NetHack/NetHack GitHub] to distribute the game.
-However, the right for persons outside of SourceForge to share NetHack does remain important. This is the era of free operating systems, like [[Debian]] and [[FreeBSD]]. Free operating systems need great free games, including NetHack. The NetHack GPL permits these free operating systems to include or provide copies of NetHack, as source code or [[compiling|compiled]] for each system and processor architecture.
