Here is a little suggestion to better support towns/nations managed by server staff rather than regular players. All of these should be set via the townyadmin town/nation command
no-upkeep flag: exempts a town/nation from paying the daily upkeep
peacefull flag: residents of the town/nation are immune to pvp. town/nation is automatically assumed neutral in war events
unclaimable flag: this town/towns in this nation can't be conquered via flag-war
No upkeep already exists - /ta toggle NPC
The other two are unlikely to happen.
