For a while we’ve been trying to help people with our unofficial Quake Live FAQ page. This page mostly includes general gameplay and customization tips and guides.
A few weeks ago, however, a more technical and official Quake Live FAQ about the game was created by the Quake Live crew.
Some of the questions answered in the official Quake Live FAQ:
What are the QUAKE LIVE System Requirements?
Where can I provide feedback, suggestions and follow QUAKE LIVE’s progress?
I am receiving an Error Code alert, what does it mean?
How can I contact QUAKE LIVE technical support?
Another effort to support players with questions is the unofficial #Quakelive.Support channel managed by B^ and supported by several other volunteers.
