Hi, this plugin I created is for easily creating a clan system that will fit into vanilla gameplay or any vanilla+ server setups. For now, it only contains basic commands, but in the future, there will be more for a more detailed clan system! I also really hope to receive feedback so I can improve my plugin (My Telegram @VcePusto).
Usage:

/clan create - command to create a clan. If you don't specify a color, it will be white by default.
/clan info - displays information about the clan you're in.
/clan delete - deletes a clan if you own it.
/clan kick - kicks a player from a clan if you own it.
/clan invite - invites someone to join a clan.
/clan accept - accepts an invitation.
/clan refuse - declines an invitation.
/clan leave - to leave the clan.
