User talk:Shawn U.S.A

Hello, I'm Materialscientist. I noticed that you recently removed some content without 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; I restored the removed content. 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 do not remove content or templates from pages on Wikipedia without giving a valid reason for the removal in the edit summary. Your content removal does not appear constructive and has been reverted. Please make use of the sandbox if you'd like to experiment with test edits. Thank you.
