some days ago I came along a new initiative from the WWF. They've just launched a new software which creations files with the .WWF extension.
They read just like Adobe PDF files, but with one notable difference: the content can't be printed!
Check out the details at:
Save as WWF, Save a Tree :*Home
Right now, I'm in the process of turning my business 'green'. Customers will either get a discount when they go for WWF-files, or have to pay a few bucks more for the printable PDF's.
The extra money charged will be contributed to the WWF foundation, but not without being doubled by my business. Customers, followers and visitors will be able to see the amount of donations using a graphic at the main website.
