Editing WoW:Useful macros (old) (section)

=== Bypass turn-in dialogue ===
 /script SelectGossipAvailableQuest(1)
 /script SelectGossipActiveQuest(1)
 /script CompleteQuest()
 /script SelectGossipOption(1)
 /script AcceptQuest()
 /script GetQuestReward(1)

This macro will do the following: 
-Attempt to bypass any initial dialogue with an NPC (such as a banker or flight-master; or any NPC with only one quest available). 

-Select the first quest reward available (can be dangerous if you get too addicted to this macro). Turn in a quest. Credit goes to www.Feign.org from back in the halcyon days of CC Rep farming when it was possible to get a quest done twice in one go - with a fast mount and mad skills.

-Do not add the command /startattack no matter how tempting it is, you'll inevitably find yourself turning in a quest in a neutral town with an opposing-faction player standing in close proximity behind the quest NPC - with hilarious consequences. Add the line /cast [insert skill/spell of choice here] at the end of macro to make it truly vital. The druid version, for example, casts Faerie Fire or Faerie Fire (Feral) depending on whether the druid is in form or not.
