Dont know if this is the right section, but here it goes...
This thread is designed to help you check to make sure you recieved the correct last name from the trader in a trade. K wat you do i s head on over to worldofwarcraft.com Go to the 10-day free trial and make an account with the same first and last name as the one of the account u just traded for. Now go into the account u traded for and do the paid character transfer... Select realm and any character. Go through the whole process and find where it says destination realm and the checkbox to trasnfer to a diff. account
Check the checkbox and put in the account name of the trial account u just made.
Now click Submit and scrool down when the page finishes loading. U should see a red box that says "Cannot be a Trail Account" if it says that then you have the right last name for the account. If it says like a paragraph of information in a red box instead of "cannot be a trial account"...then u have the wrong last name.
Enjoy!
