Hello, I'm PlanetJuice. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to Non-Euclidean geometry—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 Teahouse or the Help desk. Thanks.

Please do not add promotional material to Wikipedia, as you did to Talk:List of YouTubers. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not a vehicle for soapboxing, advertising or promotion. Thank you.
