Dear Sirs/Madams:

I am an administrator of Wikipedia (wikipedia.org), a multilingual project to create a complete, accurate, and open-content encyclopedia. Volunteers from around the world collaboratively edit Wikipedia, which is one of many projects of the non-profit Wikimedia Foundation
(wikimediafoundation.org). We depend on photography/art/diagrams/charts to clearly illustrate our articles.

Another Wikipedia editor (username: AL SAM) has uploaded an image cropped from your PDF file about the Chord project (http://pdos.csail.mit.edu/papers/chord:sigcomm01/chord_sigcomm.pdf) which can be found at http://en.wikipedia.org/wiki/Image:Chord_ring.GIF.

However, we can only use your material if you are willing to grant permission for it to be used under terms of the GNU Free Documentation License (GNU-FDL, or GFDL for short). This means that although you retain the copyright and authorship of your own work, you are granting permission for others to use, copy, and share your materials freely, and even potentially use them commercially, so long as they do not try to claim the copyright themselves, or try to prevent others from using or copying them freely (e.g., "share-alike"). You can read this license in full at http://en.wikipedia.org/wiki/Wikipedia:Text_of_the_GNU_Free_Documentation_License. Please do note that this contribution may not remain intact as submitted; this license, as well as the collaborative nature of our project, also entitles others to edit, alter, and update them at will, i.e., to keep up with new information, or suit the text to a different purpose. However, the license also expressly protects authors "from
being considered responsible for modifications made by others."

If you do agree to grant permission for use, we will credit you, state the image was based on your work and is used with your permission, and provide a link back to your website.

I hope you will consider accepting our request.

Warmest Regards,

Howard Cheng
