PerWorldMOTD
What it does
This a simple plugin which allows you to add an motd for every world you have on your server. Everytime a player switches world, it will display the motd set in the config. When a player joins it will also send the motd specific to the world he joins on. (May add a toggle for this). When a player joins a world a sound (if specified) will play.
Added PerWorld Join & Leave Messages. ie. all players in the world will receive a custom notification when a player join & leaves the world. This can be toggled in the config.
This plugin will not overwrite the motd set by other plugins (eg the Essentials MOTD). This plugin was created from a plugin request.
Permissions
The permission pwmotd.receive allows a player to receive the motds. (Might add per world receive perms)
Commands
I may decide to add an in game command to edit/add motds.
Config
An example config can be found here.
