Welcome and thank you for experimenting with Wikipedia. Your test on the page List of Egyptians worked, and it has been reverted or removed. Please take a look at the welcome page to learn more about contributing to this encyclopedia. If you would like to experiment further, please use the sandbox instead. Thank you.
