The original blank space between boards and at the top was based on the original side margin. The original side margin I gave was 100px. This number was given before we discussed responsiveness. Now that we're using responsiveness we will no longer be using the 100px size. Therefore I think these vertical blank spaces should be adjusted too.
You can see in this thread that big will have 90px and medium will have 30px.
Bases on this I think the vertical areas for bread crumbs and subscribe should be 60 pixels (currently 50). The area between boards should be 30px (currently 25).
