I have been on other servers where players were able to receive their head as a placable item. It will be a great way to display people and might get people to want to donate to the server for this perk.
All of the higher donator ranks have /hat but he means having a head, like a zombie or skeleton head, but in your own personal skin. It is a plugin but i don't believe this server has it.
