I particularly valued (eventually) being linked to the whole document -- not just he problem tree. The FAO website was not easy to obtaint he full document from, however, and your clietns in developing countries might have difficulty as it was encessary to download a zip file to get the full document. This was not explained and not intuitive: I foudn it by a process of trial and error.

Editor's note: Many thanks for your comments. We have edited the text related to the link and hope that we have made this more clear.
