Quake discussion fora

Here are some forums to find Quake discussion outside of social media, for Quake aficionados who like to dig into the culture.

In alphabetical order:

* func_msgboard

* InsideQC forums

* Quaddicted forums

* Slipgate Sightseer

The first two are more focused (or so it seems to me) on Quake development and the last two also discuss gameplay.
