AnnounceInterrupts

This is the addon announces in chat when you interrupt a spell. It is lightweight and fully configurable.

To bring up the configuration interface, type /ai or /announce interrupts.

You can also reach it through the interface options.

In the configuration you can choose where you want the addon to be active (raids, party instances, BGs, arenas, etc.), as well as the message to be printed when you interrupt and which channel to print it in.
