How can I disconnect a twitter account from photo booth on my mac?

[Miss]

A friend of mine used photo booth on my mac the other day and decided to tweet one of the photos, to do this she connected her twitter account to it. I can't see any options to change or remove accounts and I keep getting notifications from her twitter. How can I get rid of this?

I'm using a macbook pro with OSX mountain lion

She has connected Mountain Lion, not Photo Booth to her account. Open the system preferences by clicking the cog icon on the dock, and then click onto the Mail, Contacts, and Calendars option in the preferences pane. You will see a Twitter account listed in the accounts; select it, and then click the - button at the bottom of the list. This will remove the Twitter account from your computer.

I hope this helps.
