Is there a way to allow PVE on weekdays and PVP on weekends? Perhaps an option to enable/disable PVP with the Custom Restart Config. My community has been requesting this limited, "purge" style PVP and I'm afraid I can't always be available to manually update these settings. Please consider this!
I've been very happy with SurvivalServers' quality and look forward to a response.
