Hello, I'm Materialscientist. I wanted to let you know that I reverted one of your recent contributions —specifically this edit to List of waterfalls by height—because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help desk. Thanks. Materialscientist (talk) 04:23, 12 June 2020 (UTC)

Please do not add promotional material to Wikipedia, as you did to Iguazu Falls. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not a vehicle for soapboxing, advertising or promotion.
