I suspect that most if not all of these messages are "just for fun", but I love getting them anyway - also, on my last patrol BdU asked me, if possible, to go patrol another grid square. I was just wrapping up my 24 hours in my originally assigned grid, and the new one wasn't that far away, so I decided to go there for a lark - turned out I spotted and sank 3 freighters when I got there, so now I'll always go if I can, just in case
