In Memoriam

In Memoriam, also known as September 11 Wiki, was a wiki dedicated to who died in the terrorist attacks of September 11, 2001, in the .

The wiki was originally a fork of English Wikipedia. It was created in October in response to a flurry of  pages for 9-11 victims that were deemed not to belong on . The solution was to create a separate Wikipedia to cover the attacks - sep11.wikipedia.org - a move unique in Wikipedia's history, and a sign of its still-uncertain scope and direction in 2001. According to Wikipedia's article on itself, In Memoriam was the first sister project ever created for Wikipedia. When the creation of new memorial pages for 9-11 victims died down on the English Wikipedia, activity on the September 11 Wikipedia mostly ceased as well.

Concern eventually surfaced that a wiki dedicated to memorials for the 9-11 victims violated Wikimedia's mission of a collection of wikis with a neutral, worldwide point of view. Discussion on whether to delete the wiki began in 2006. On September 15, 2006, it was made. Sometime in 2007, the content was moved to its new location, www.sep11memories.org, no longer hosted by Wikimedia. The original sep11.wikipedia.org was finally on 22 June 2008.

In August 2010, the wiki was reported as, and it has not been restored (as of March 2013).
