This addon announces your successful interrupts to say/party/raid channels including when you interrupted as well as what spell (with link) was interrupted.
On some fights interrupting certain (boss) abilities is essential to winning the fight. This addon allows you to announce it, if you made an interrupt, but unlike a macro it only prints a message, if you actually did interrupt something, not if you pressed the button too late for example.
As a very simple assistance for interrupt rotations you can make it so, that the next person in line after you is named if you announce your interrupt. At this point this is very very rudimentary, but it might be expanded upon in the future.
Configuration:
Type /ia to open the configuration dialog or go to the addon section in the blizzard standard interface and choose the tab for Interrupt Assist.
This is an initial release. I have several additions planned as my time (and motivation) permits.
