My user name is 'onthecouch' on my Macbook Air, and on my iMac, when I hit "Finder" it shows up on the left column, and I can drag that into the dock to always be there. For some reason, I don't see that in my Air. When I click Finder, I only see "All My Files, AirDrop, Application, Desktop, Documents..." etc., but not my actual user folder. How do get it there? Thanks.
