Developemnt and use - Training manual

[George Farris]

https://wiki.ubuntu.com/Training

This site has an Instructor and Student training manual for Ubuntu.  The
license says share and add to but not for commercial use.  Why ion earth
would you not allow Educational Institutions to use this material in
classes.  I find this very strange.  

Possibly the license could be tweaked to at least allow training people
with this material.

If anyone has any information about this I would be very interested.

Cheers all.
