So with factions installed, a problem has appeared. Players can invite others to their faction, set their home outside of the prison, and any faction member can /f home bringing them out of the prison. Not sure if you can, but could an admin make it so only free has the permission to /f home? Or join factions overall?

Another thing, faction members can claim the prison. I had to do it earlier when I invited Novgigi to my faction because he was stuck in spleef, with /spl back not working. I invited him to my faction, claimed part of spawn, set my home, had him /f home, and it worked. So, it was good to be able to get him out, but others may claim the prison.
