Did that for a while but there was some negatives associated with the solution (in our enviroment)
1 manual X 2 formats X 2 archive formats X 18 courses = a lot of links
A lot of links on different pages = difficult to keep updated and not too pleasing on the eyes.
Its that form over function argument again ...
I'll see if I can come up with something... Else will revert back to the many links option (or change our minds about tracking downloads of the manual)
