NICE PLUGIN!!!
It works perfectly and doesn't seem have an error like the comment below!

Keep working on it dude! You help me in my project any other plugin doesnt give this options without add unnecessary options :D

The plugin itself is actually great but when a player joins or leavs there is this error:
[Server thread/ERROR]: Could not pass event PlayerJoinEvent to UltimateChatFormat v0.5
