I have had the opportunity to read, and to review, all of the English Wikipedia articles, materials, and various lists related to the September 11, 2001 terrorist attacks on the United States; and I want to thank, and to congratulate, everyone who contributed. Wonderful job! It is an excellent example of what a truly collaborative community can do.
I would agree that the coverage is excellent, but turbulence does emerge upon occasion (for example, on the Controlled demolition theories 9/11 article). Our progress on the subject area can only continued if our contributors maintain their levels of professionalism and if the project's administrators continue to be vigilant for problematic conduct.
