As someone belabored, truthers haven't been able to even add a link to a WTC 7 collapse video to Wikipedia's WTC 7 article, and I decided to try to do something about it. Here's Wikipedia's WTC 7 page:

http://en.wikipedia.org/wiki/7_World_Trade_Center

Interestingly, the WTC 7 article has been selected as

"a current featured article candidate. A featured article should exemplify Wikipedia's very best work, and is therefore expected to meet several criteria." (see the discussion page)

Anyway, I added this to the section entitled "Collapse":

There are numerous resources for viewing the collapse of 7 World Trade Center on the Internet, including [http://video.google.com/videosearch?q=collapse+of+wtc+7 Google Video].

I also added a link to a Google video of WTC 7's collapse to the External Links section.

Finally, to test the waters, I added NIST's statement that "No steel was recovered from WTC 7" to a relevant section.

All the changes were quickly reverted by different users. When I responded by undoing some of the reverts (and arguing that users should be encouraged to view videos of this major building disaster), I was directed to Wikipedia's "three revert rule" policy, based on which an editor can be blocked if he or she makes more than three reverts during a 24-hour period.

So, a number of Wikipedia editors seem to be collaborating in an effort to prevent the addition of anything that might challenge the official story, at least in the case of the WTC 7 article (and that is easy to see by reading the article). Obviously, one or two truthers are not going to be able to change this. Many more would be needed. The question that needs to be asked, of course, is: Is it worth the effort? How much reader traffic does a typical 9/11 article from Wikipedia get?

Be this as it may, if someone knows of a WTC 7 collapse video that does not infringe on any copyrights etc, I'd appreciate a link. All advice regarding conflict resolution etc. on Wikipedia would also be helpful.
