Is there a way to change the AutoTweet messages used by TweetCraft?
Yes, although if the TweetCraft addon is updated again, you would have to manually update these changes. To do this, go to your Warcraft installation directory: World of Warcraft\Interface\AddOns\TweetCraft\AutoTweets\ folder. Inside, you should see a list of Lua files for tweets that have been registered (by default this would be Achievements.lua and Movement.lua). Open these files and search for “#wow” which is the default hashtag for the message being sent and customize this to your heart’s content.
