Thanks for uploading File:Diagram2 copy.jpg. 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, then a link to the website from which it was taken, together with a restatement of that website's terms of use of its content, is usually sufficient information. However, if the copyright holder is different from the website's publisher, their copyright should also be acknowledged.

As well as adding the source, we also need to know the terms of the license that the copyright holder has published the file under, usually done by adding a licensing tag. If you created/took the picture, audio, or video then the ((GFDL-self)) tag can be used to release it under the GFDL. If you believe the media meets the criteria at Wikipedia:Non-free content, use a tag such as ((non-free fair use in|article name)) or one of the other tags listed at Wikipedia:Image copyright tags#Fair use. See Wikipedia:Image copyright tags for the full list of copyright tags that you can use.

If you have uploaded other files, consider checking that you have specified their source and tagged them, too. You can find a list of files you have uploaded by following this link. Unsourced and untagged files may be deleted one week after they have been tagged, as described on criteria for speedy deletion. If the file is copyrighted under a non-free license (per Wikipedia:Fair use) then the file will be deleted 48 hours after 14:46, 27 March 2010 (UTC). If you have any questions please ask them at the Media copyright questions page. Thank you. Salavat (talk) 14:46, 27 March 2010 (UTC)[reply]

Thank you for uploading File:Singapore Presidential Elections Procedure.png. However, it currently is missing information on its copyright status. Wikipedia takes copyright very seriously. It may be deleted soon, unless we can determine the license and the source of the file. If you know this information, then you can add a copyright tag to the image description page.

If you have uploaded other files, consider checking that you have specified their license and tagged them, too. You can find a list of files you have uploaded by following this link.

If you have any questions, please feel free to ask them at the media copyright questions page. Thanks again for your cooperation. FASTILY_sock^(TALK) 03:07, 28 March 2010 (UTC)[reply]

On 19 September 2010, Did you know? was updated with a fact from the article Presidential elections in Singapore, which you created or substantially expanded. You are welcome to check how many hits the article got while on the front page (here's how, quick check ) and add it to DYKSTATS if it got over 5,000. If you know of another interesting fact from a recently created article, then please suggest it on the Did you know? talk page.
