Save your work as .wwf and eliminate wasted paper

Every office worker has witnessed the piles of unclaimed documents that sit on printers everyday.  Multiply this by the hundreds of thousands of businesses around any given country and then again by every working day of the year and you have a huge amount of wasted paper.  Trace that back further and you have forests around the world being needlessly cut down, scores of trees taken out of the environment just to sit on companies printers.

Surely there is something that can be done?  Enter the WWF, who have taken the innovative approach of tackling, not the offenders, but the documents themselves!  Now its possible to save any document as a .wwf, a new file format that simply cannot be printed!
