Since the release of ArmA Reforger two weeks ago eRazer and Joe90 are trying to resurrect MACE from the ashes it has been for a few years now.
ArmA 3 server was converted to ArmA Reforger server (lookup MACE in your multiplayer server browser). There is an ongoing memory leak issue with the Reforger server software since the first release and as soon this goes away we will organize an event around Conflict scenario (to begin with).
Keep an eye on the events tab, we will add the event details there as soon as the server becomes stable.
