Hello, I'm Martin of Sheffield. I wanted to let you know that one or more of your recent contributions to Talk:Mercury (element) have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks. After 4 years without warnings being posted, this address is being used for petty vandalism again. Please stop at once. Martin of Sheffield (talk) 21:42, 14 December 2017 (UTC)
