User talk:Tu A.Tordes

Hello, I'm NawlinWiki. I wanted to let you know that I undid one or more of your recent contributions to Chemical reaction because it did not appear constructive. 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!
