okay listen...
anyone who can add/remove tags for Kingdoms knows this already.
Kingdoms use a special tag system, it DOES NOT USE THE GUILD MANAGER. Basically when you are near your 'tag helper' npc which is located near or inside your Kingdom castle, you can add tags using the following syntax:
add <kingdomname> <accountname> <nickname>
remove <kingdomname> <accountname>
if I wanted to add account name J786 to Dustari, with the nickname of Jules and the rank of Squire, I would type this
add dustari J786 "Squire Jules"
see? once you add, you can't "list" the members, they are just THERE. You can remove them, but only if you know their account name. There is no viewable database for your members.
All Kings are SUPPOSED to ask a new recruit if they are in any other kingdoms before they can join, but sadly they DON'T
Not only that, but some people lie about it. That is why we need a new system
