This addon allows you to predefine up to 15 chat messages you want to send, and then send them all at once. You can customise each message individually:
1. Choose chat channel you want to send it to (guild, raid, whisper, etc)
2. Channel number/player name (for custom chat channels or whispers)
3. Message text
NOTE: sending more than 10 messages at once will usually result in a delay, but messages will be sent eventually.
