The wiki is still there!
But currently the information in Nexuiz/Docs/server is more uptodate then the info in the wiki or forum.. Actually i think its better this way and will only update my server setup posts in the forum to explain some bits maybe.. But i need some time to do this.
Well help with improving documentation is always welcome. I just think for people already familiar with quake dedicated server Nexuiz is not much different and what is there should already be enough for those. Maybe someone 'fresh' can help with finding spots unclear to beginners..
