Signing out/exiting from Ubertwitter

Hello, I have just downloaded ubertwitter on my blackberry. I want to know if you can sign out from your twitter account on it? Also when I exit the application and its not running is it turned off then. So when its exited and turned off it wont be using my internet time?

You can sign out. Just go to the options and sign out of the account.

And yes, when you completely exit the app it's not running, so no internet/data time.
