1. Command to disable flag

Very good plugin. I hope to add the ability to display countries by IP when joining

This guy is a madlad! I just asked something for him and added, so in exchange I'll leave this ratings just 'cause the plugin rocks and he also rocks!

Incredible and amazing! I would love to see the LGTBIQA+ flags also it it was possible since our server it's from that theme! Also, here you have 5 stars! Loving your plugin <3
