We have many possible commands that can be set in place to help protect you guys beyond our plugins.
So to help protect you guys im going to help you guys out. Alot of these are known but not by everyone.
To keep all outsiders out of your town use /town perm town set out none
That command would prevent all outsiders from entering the towns claimed land, It will not affect town members, or town friends. Town friends can be added by town mayor, and town assistants.
And one I always make sure to set in place is /town perm town set friends enter
There should be little reason to give a friend build perms, though sometimes there is reason. And by default friends get build perms. If you have a reason to give a friend build perms make sure that after you set it back to /town perm town set friend enter
And my favorite of all applies to town residents, but not town assistants.
You can set plot permissions, a plot is 1 chunk. which is 16x16.
To do this you enter /assignplot <name>
That will make that chunk owned by whoever's name you put example /assignplot DonVanhugenstyn
Once you do that town residents who do not own that plot get reduced permissions, and you can use commands to change them. like /town perm plot set town enter which would allow town residents to enter but no build perms. Once you use /assignplot <name> it automatically takes on whatever perms the town has set but you can as I said change the perms for that specific plot.
With /assignplot you can have members within your town and not worry about theft. If someones gained your trust you can promote them to town assistant and then the plot assignments wont affect them. However please be careful who you let into your town and give assistant rank to. We cannot stop anyone from stealing from you if you have given them permissions to allow them to do so.
/town perm town -will give you current town permissions set
/town perm plot -will give you the current set permissions of the plot you are in
to change entire town permissions is /town perm town set <name> <permission>
ex. /town perm town set out none - out is the name, none is the permissions, meaning "out" gets "none" meaning no permissions to outsiders, not even entry into the town
to change plot permissions is /town perm plot set <name> <permission>
ex. /town perm plot set town enter -means your setting the plot permissions for "town" to "enter" so residents can enter but nothing else. remember town mayor and town assistants aren't affected by plot permissions though.
Remember, choose your town assistants wisely. They can do everything a mayor can except delete the town.
