what to do when i find some irrelevant and advertising data on a page that should be kept (not viable for deletion)?

Be brave! The wonder of Wikipedia is that you can change any article you want. Funnyfarmofdoom (talk to me) 19:33, 4 March 2013 (UTC)Reply
Thanks for quick response. I found a page with some personal contacts and other irrelevant things. I have removed those things but i don't know what to comment when submitting the article (type of edit which was done on the wiki page).

File Copyright problem

Thanks for uploading File:Yashveer Singh social entrepreneur.jpg. However, it currently is missing information on its copyright status and its source. Wikipedia takes copyright very seriously.

If you did not create this work entirely yourself, you will need to specify the owner of the copyright. If you obtained it from a website, please add a link to the page from which it was taken, together with a brief restatement of the website's terms of use of its content. If the original copyright holder is a party unaffiliated with the website, that author should also be credited. You will also need to state under what licensing terms it was released. Please refer to the image use policy to learn what files you can or cannot upload on Wikipedia. The page on copyright tags may help you to find the correct tag to use for your file.

Please add this information by editing the image description page. If the necessary information is not added within the next days, the image will be deleted. If the file is already gone, you can still make a request for undeletion and ask for a chance to fix the problem.

Please also check any other files you may have uploaded to make sure they are correctly tagged. Here is a list of your uploads. If you have any questions please ask them at the Media copyright questions page. Thank you. NtheP (talk) 15:42, 12 March 2013 (UTC)Reply
