User talk:197.156.77.138

Hello, I'm Materialscientist. I noticed that you recently removed some content 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.

Please stop your disruptive editing. If you continue to vandalize Wikipedia, as you did at Template:Contributing to Wikipedia, you may be blocked from editing. Stikkyy (talk) 00:19, 12 January 2017 (UTC)
