so does
/console synchronizeSettings 0
make it so my macros are stored locally only? I want to run 2 different setups. TankA and 4 shaman and TankB and 4 shaman, which I figure I need different folders of WoW and different macros for all characters. Is this feasible?

edit: Also, do you type the above in your chat screen? Or do you save it in a config file? Is it permanent until changed?
