that is what i used on my druid, now i havent played my druid in months so im not sure if macro coding changed in that time but last time i used it, if i was in a raid it would announce my innervate target in raid chat, if i was in party it would announce in party chat.
also used the same model for res target announcements
When I cast Tricks of the Trade, it sends a whisper to the person that I tricked. When I kick, it let's the group (use this mainly because I wanted to know) that I interrupted a spell. It sends a message when I sap/blind someone and then tells me when it ended.
Great addon for announcing various spells/abilities.
