HyStaffChat
HyStaffChat is a StaffChat plugin allowing your staff members on your server to communicate in a private chat. This plugin also has a feature that allows players to use the same command that staff use to communicate in the Staff chat but instead to message any staff that are currently online. You can also fully customise the messages in config.yml.
