How to.....?

How do i check what chars there is on a frozen account?
Wow is btw not installed.

There is no easy way, unfortunately. The only thing you can do is check every single server under the paid char transfer menu.

That does take hours, and is very annoying. It's the only method available, though.

You can also try to check if that account did any recent paid character transfers. If it did, it shows up to what real it was transfered and its probably the realm of his main characters.
