Hello, I'm Materialscientist. I noticed that you made a change to an article, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Materialscientist (talk) 09:51, 7 August 2013 (UTC)

Hello, I'm Plantsurfer. I noticed that you recently removed content from Natural gas without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.
