- I'm currently not active on WoW, so won't be updating this addon any time soon. Follow the below instructions and the addon will hopefully work with whatever version you're playing for a while -

You can for the most part download whatever version of this addon was updated most recently, and tell the game to "Load out of date AddOns" in the top right of the addon menu, and any version of this addon will likely work.

Legion specific features:
- Automatically selects the option to open the Rogue Order Hall doors in Legion from all 3 NPCs.

Notes:
- You'll know when Auto Gossip has activated by seeing a small message in your chatbox.
- Auto Gossip will cancel out automatically if the NPC has quests available or active to avoid overlaps and clashes with other similar addons.

Hold down any modifier key (shift / ctrl / alt) whilst right-clicking the NPC to Cancel all addon functions and show the dialogue options as normal.
