After patch 4.1, I had to update some macros for few friends and they let me access their accounts to do it, to find out that the server does not stores the macros anymore in this patch for now.
Used to be able to login from anywhere and edit any code in the macro and after logout being stored in the server, so they could be happy with an updated macro, but no, is back to storing the data under your Account name folder inside the WTF folder in the WoW located game folder. Sad face if have to carry with me this file in order to have my macros any other computer I would like to log.
Folks don’t forget to logout after setting up a macro so it saves the data!
