This is a simple addon to assist others in the same zone as you when you find a rare. It will announce the rare's name, current health, engaged or not, coordinates, and provide a push pin to quickly locate the mob. Death announcements are also provided so others won't waste their time coming to your location only to find a death mob.
Announcements are sent via chat links when you target a rare mob that is tracked. Due to API changes made in 8.2.5, announcements cannot be sent automatically. It requires user interaction, such as clicking the link in the chat message when you target a rare or when a tracked mob dies.
