This is a great Plugin. I love it a lot. It helps with my faction server because when someone gets raided, they know immediately :D You should make more Plugins. But also, you should add a sound so you get notified when you get tagged :P
ChatMention is a useful plugin for thoughs who miss chat messages directly to you because thoughs chats are damn to fast. Well this plugin will assist you in that matter.
This is a very nice plugin.
I have a feature that could be a nice addition - Maybe adding a sound when you have been mentioned so if a player is AFK browsing they will get a sound that a player calls them.
