I have been going through my scripts archive and I have found several scripts I made ages ago that I haven't released. Thus I figured I'd release some of them!
This is a World Message broadcaster. The reason I made this script was because Mangos didn't have a broadcast system like Trinity did. However, this script should work for any core running Eluna.
Simply add your messages to the top table structure in the script. You can choose between a timed message in seconds, or a specific time and day of the week. How this is set up is explained further at the top of the script.
