User talk:Kostaskal

Hello, and welcome to Wikipedia. We appreciate your contributions to the Chromatography article, but for legal reasons, we cannot accept copyrighted text or images borrowed from other web sites or printed material, and as a consequence, your addition will most likely be deleted.

You may use external websites as a source of information, but not as a source of sentences. This part is crucial: say it in your own words.

If the external website belongs to you, and you want to allow Wikipedia to use the text — which means allowing other people to modify it — then you must include on the external site the statement "I, (name), am the author of this article, (article name), and I release its content under the terms of the GNU Free Documentation License, Version 1.2 and later, and under the terms of the Creative Commons Attribute Share-Alike."

You might want to look at Wikipedia's policies and guidelines for more details, or ask a question at the "Help Desk". You can also leave a message on my talk page. Materialscientist (talk) 22:11, 15 August 2013 (UTC)[reply]

Blog

Hi, Kostaskal. I have noticed that all your contributions include links promoting one blog, presumably yours. This type of promotion is not appropriate on Wikipedia. In addition, content should be referenced to reliable sources and blogs are generally not included. Please have a look at WP:REFSPAM, WP:RS, and WP:COI for additional information. Thank you. -- Ed (Edgar181) 21:46, 6 November 2013 (UTC)[reply]

Please stop adding inappropriate external links to Wikipedia. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you may be blocked from editing Wikipedia.
