Low level quests
 

Simply put, how can I show low level quests on the map?

Turn 'Quest Givers' on - Yellow button on the quest tracker toolbar (if it turns blue it's only showing dailies)
Click the priorities button on the quest tracker toolbar (2nd button on the left)
Slide the 'Quest Giver Lower Levels To Show' slider all the way to the right (80).

Edit: I think we'll make this the default setting in the next release.

I agree with what you said in the other thread. The priorities thing is indeed confusing. I thought that putting the priority higher for low level quests would just make low level quests come first in the order you want to do the quests.
