Hehe i know u wont give me such char
Tho when u call them for recalling in the best case they will require:
-Full name of owner of the account
-Full adress
-Secret question + secret answer
-CD Keys
In worst case they will want also scanned picture of your ID.Also once wanted from me my ID card and the WoW box in one frame picture.
If you go for changing the answer im sure they will require ID picture.
