Please refrain from making unconstructive edits to Wikipedia, as you did at Samy Mahmoud. Your edits appear to constitute vandalism and have been reverted or removed. If you would like to experiment, please use the sandbox. Administrators have the ability to block users from editing if they repeatedly engage in vandalism. Thank you.
