Android 4.0 tablet.
Have Skype installed. i can close down skype application, but it does not sign me out. as a result anyone who picks up my tablet has access to my skype account. HOw do i sign off skype so that when I launch it again i (or another user) is forced to sign in?
On the latest Skype for Android 2.6 you will find an exit button on top right of the main screen of the app (that screen is shown when you click the Skype icon inside the app).
