Open world of warcraft folder/interface and /wtf

open shared wow folder form main computer

/copy

"Are you sure you want to over-write?"

Then go in to wtf, change the account number from a 1 to a N
then go in to the accoutn and change from EVEY to EWEY

total time * 5 is like umm 5 mins, maybe once a week at most?
