Hi, I just had an idea that would help me a lot to improve my server if I apply it, but for that I need a plugin that does not exist. It is about building a plugin that allows users to enter which user has invited them to the server. This will help me and other servers to give prizes to the person that most people have invited. I think it's not a complicated job, it's just about creating a command that can only be executed once per person and that gathers the data entered. This can be improved by creating tops, rewards (commands) when reaching a number of guests and much more. Sorry for my bad English, I speak Spanish.
