Is it possible to change to message when a player joins an arena?

[Codecrafter14]

I'm using a nick plugin and I want to change to join message. The nick plugin provides a placeholder with the nicked name, and if the player is not nicked, the original player name. I didn't found anything in the config...

This plugin (like most of the plugins) uses display names instead of player name, because these names are changeable by plugins. Your nick plugin should be able to change display names. And if not, consider using a different nick plugin.
