If you don't know what bleed is, I don't have time to explain properly just now.
But, in a nutshell, it allows you to have pages where the pictures, backgrounds etc go right to the edge. This is a basic publishing task which you would expect a program called 'Publisher' would be able to cope with.
You know that 50 page book I was talking about?
Have I designed it in Publisher? Yes I have.
Does it have pictures etc going to the edge? Yes, it does.
Do I have time for all this nonsense? No, I don't.
Time to listen to this song again, I think...
(Edit: I have found a way to do this)
