The [FGS] Clan

After playing Killzone 3, a game where you have to choose your classes in multiplayer, I remembered how I really liked DXAG. I'll be changing my server from Tac to DXAG. So I have questions, Is there anything special about hosting DXAG servers? Do I have to get permission from somebody? Where can I get the files for it? What are the steps for converting maps to DXAG?

I'm pretty sure Nobody played a part in development he should be able to help out.
