Quest Timer accounts are separate from AC accounts... You can have whatever characters from any AC account under the same username and password for Quest Timer. If you don't already have a Quest Timer account, just pick a username and password (not your AC username and password), type them on the Internet > Settings tab, and click Upload Now to create the account. You don't NEED a Quest Timer account to use Quest Timer, all it does is stores your quests file on my server so that you can have the same quests file if you play AC from more than one computer.
