new user account defaulting alias

[greenteagod]

I have created a new user account on my mac, and no matter how many times I change it, Adium reverts back to the name of the user account as the "alias" instead of what I've set as the alias in Adium itself. The preferences reset after restarting Adium.

Is there a plist somewhere or some setting that I need to adjust to have the alias I set in Adium be retained?
