Macro to check if you've done the 4 world bosses

/run for k, v in pairs({ Galleon = 32098, Sha = 32099, Nalak = 32518, Oondasta = 32519}) do print(format("%s: %s", k, IsQuestFlaggedCompleted(v) and "\124cff00ff00Yes\124r" or "\124cffff0000No\124r")) end

Found on wowhead comments: HERE and thought it would be worth sharing since I feel it's better than an addon. 

Enjoy!
