Legacy (IRC channel)
#legacy is the official channel for the Doom Legacy source port. It was registered on the Freenode IRC network on January 11th, 2004 by xiO. On June 15th, 2021, the channel was migrated to the Libera IRC network after a contentious change in Freenode's management and subsequent wiping of all channel and nick registrations. The current channel operator is Dennis Meuwissen (Exl). The channel is now largely defunct with only a few active participants remaining.
In its heyday, #legacy used to have a resident bot, Demis, which was used to both store information and generally insult people.
As is often the case with IRC channels, #legacy's conversation was of a light hearted and somewhat irrational nature. Very little was taken seriously and the conversation rarely involved Legacy as a topic.
The #Legacy Doom Launcher (archive.org link), written by xiO, is a plugin for mIRC. It allows people in #legacy to host and join multiplayer internet games in Doom Legacy.
