Hi, I have recently gotten griefed on my server so I wanted to add this plugin. It is called NoTNT.
Plugin Description: NoTNT, a very simple tool to prevent the abuse of TNT. This plugin is configurable with a custom usage permission node, as well as a message.
Plugin Download: https://www.spigotmc.org/resources/notnt.24976/
*Also side note is there going to be development to be able to add schematics into Aternos?
