So it has to be compatible with regios, all you have to do is make it so a player right clicks a sign that reads something like [example] second line Region Name third line price to buy to get in. The player can buy access to the region. But multiple players, can be added to the same region. You could go even farther, where players can buy access to a appointed region, and you can set flags to what they can and can't for example flag so they can not break a certain block. Just a idea if you make this i'd be happy
