License tagging for File:Worker.png

Thanks for uploading File:Worker.png. You don't seem to have indicated the license status of the image. Wikipedia uses a set of image copyright tags to indicate this information; to add a tag to the image, select the appropriate tag from this list, click on this link, then click "Edit this page" and add the tag to the image's description. If there doesn't seem to be a suitable tag, the image is probably not appropriate for use on Wikipedia.

For help in choosing the correct tag, or for any other questions, leave a message on Wikipedia:Media copyright questions. Thank you for your cooperation. --ImageTaggingBot (talk) 02:05, 26 February 2011 (UTC)[reply]

File source problem with File:Worker.png

Thank you for uploading File:Worker.png. I noticed that the file's description page currently doesn't specify who created the content, so the copyright status is unclear. If you did not create this file yourself, you will need to specify the owner of the copyright. If you obtained it from a website, please add a link to the website from which it was taken, together with a brief restatement of that website's terms of use of its content. However, if the copyright holder is a party unaffiliated from the website's publisher, that copyright should also be acknowledged.

If you have uploaded other files, consider verifying that you have specified sources for those files as well. You can find a list of files you have created in your upload log. Unsourced and untagged images may be deleted one week after they have been tagged per Wikipedia's criteria for speedy deletion, F4. If the image is copyrighted and non-free, the image will be deleted 48 hours after 02:36, 26 February 2011 (UTC) per speedy deletion criterion F7. If the file is already gone, you can still make a request for undeletion and ask for a chance to fix the problem. If you have any questions or are in need of assistance please ask them at the Media copyright questions page. Thank you. Eeekster (talk) 02:36, 26 February 2011 (UTC)[reply]

Great work on implicit contracts

Thanks for your revision of Implicit contract theory. I made a few changes based on grammar and the Wikipedia Manual of Style. You clearly know more about the implicit contracts than I do, but the content looks great. You did an incredible job considering this was your first article. Please keep up the good work. Many of Wikipedia's economics articles need improvement. Please contact me if you have questions about Wikipedia.--Bkwillwm (talk) 03:56, 9 March 2011 (UTC)[reply]
