The SteamLUG community is an amalgamation of several communities which previously existed independently.
The Linux User Group on Steam was created by vorot93 as "We Want Linux Client!" in April 2010 as a petition-like effort to gain Valve's attention. It gained popularity and quickly achieved the critical mass needed to sustain its position as the biggest Steam group of Linux users on Steam, and continued to grow in spite of its dormancy. In 2012, the current group admin Zenitur handed ownership of the group over to Cheeseness, who brought the group back into an active state and merged it with the existing SteamLUG IRC community to coincide with the release of Steam for Linux.
In March 2013, a SteamLUG community member from Valve offered to assist with changing the group name.
Prior to the introduction of Steam for Linux, discussion of Linux on the Steam Powered User Forums was confined to a single thread, bringing together people of varying backgrounds and creating engaging discussion. The current iteration of the Linux Thread was created by madrang in May 2011, and accumulated over 4,000 posts before the end of 2012.
Registered in 2011 by meklu following discussion in the SPUF Linux Thread, the #SteamLUG IRC channel became a place for the active members of the SteamLUG community to gather and plan their respective projects. As activity in the SPUF Linux Thread slowed, the IRC community continued to grow. When the Steam for Linux beta was released, the average number of users more than doubled, bringing in a swath of Linux gaming enthusiasts.
In March 2013, through the efforts of swordfischer, meklu and Cheeseness, SteamLUG.org was launched to provide a hub for SteamLUG's many faceted community, giving centralised access to community news, upcoming event information, details of SteamLUG's game and Mumble servers, webchat access to IRC, and a portal for upcoming SteamLUG projects.
Whilst developing SteamLUG.org, several libraries were created, which can be found in SteamLUG's repositories on GitHub. Forks and contributions are welcome.
SteamLUG.org also makes use of xPaw's PHP-Source-Query-Class library, Vojtech Semecky's lastRSS, and edmundask's MurmurQuery.
