I just got exalted with Kirin Tor. I did this by running instances and did every quest that rewards reputation to that faction. To do that, i had to search quests that gives reputation to Kirin Tor from Wowhead. I found huge list of quests and had to check manually (going to the guy who gives the quest) and doing it if it's available.

I was wonderin that is there an addon, which tells you every quest for x faction that is still doable by you which would make getting other factions exalted aswell.
