Firstly, I am going to put text with the icons, so the user won't be completely clueless and as confused as a whale hurtling through the air from a great height.
Our WinForms application's user requirements has been added to and we now need to give the users the ability to log out of a server and then log back in, not just exit the application.
The icon that we're currently using on our menu bar to represent exiting the application is a "0/1" image, similar to, but not as stylish as, the image below:
The Crystal icon pack has a circular-type icon that reminds me very much of sleep/dreaming or magic/"poof" - the interjection, NOT the offensive slang word!
Door icons seem like they might be a good fit, but then again it could represent exiting the application to many users (and I just plain-well don't like those "door" type of icons :-)
My personal bias aside, what do you recommend? It is possible to change the Exit icon if need be.
