I am a PVE server, how to set up team members to hurt each other

"players can hurt players" in the ruleset should allow it.  I suppose this will be in a specific zone, otherwise I am not sure why you need this plugin.

I'm curious about this as well. I have clan members wanting to toggle FF so they can PvP with each other. Would it possible to do this and not have their fire damage/kill other players? I'm guessing it would require an update to the plugin.
