From the patch notes:

"Macros and key bindings are now saved server-side so there is no longer a need to reconfigure them when logging in using another computer."

I knew this was coming but didn't think much of it and being far from a computer genious, are we going to have to make this transfer, i.e., create all new macros and key bindings or can the WoW servers somehow pick up on the settings on our computers?

Thanks.
