Hello, I'm Jschnur. I wanted to let you know that I undid one or more of your recent contributions to Potassium aluminium fluoride because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted. Take a look at the welcome page to learn more about Wikipedia. Thank you.
