It may be too complicate to them to download, install and open the file; figure out to open each individual and look in the different tabs to view the information.
The online report as suggested is a great and free option to share your information. It requires a plugin to view the graphical tree in svg format but it's based on Adobe's business model... so easy to install
Beside the svg, the online report requires no installation at all, and works on any computer...
