Admittedly, I've not been able to allocate much time to this project in recent years: most updates have been driven by an occasional external contribution. This is a great plugin, it deserves more love! If you're a developer and want to help maintain Pet Master, you're welcome to do so. Let me know and we can discuss giving you access to this repository and to the Bukkit/Spigot resource listings. 😉

@BigTallahasee will be taking over maintenance of this project. Please join me in welcoming him and wishing him good luck! If any other developers are interested in helping out as well, feel free to reach out. 😉

I'm currently working on updating the message system of PetMaster to the MiniMessage system, as it is currently very inconsistent and doesn't really support coloring. Hope this is in your interest.
@BigTallahasee (gonna Ping you too as you are maintaining this plugin as well)

@Xaver106 Hey thanks :) I don't see any issue with this. If you would like to help or contribute in anyway do feel free as the project is open source :) Just submit a pull request
