Hello, and welcome to Wikipedia. We appreciate your contributions, 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) 02:12, 8 August 2013 (UTC)
