Lost Ottawa on Facebook

There was a lot of local media coverage last week for Lost Ottawa, a Facebook community site devoted to images of Ottawa and surroundings dating from the founding of the city to the year 2000. It's now coming up on 10,000 Likes.
There's a CBC page featuring the community founder, David McGee, at http://www.cbc.ca/news/canada/ottawa/story/2013/07/03/ottawa-lost-ottawa-facebook-page.html
If you have historic Ottawa photos, and that includes organizations that may have a wall of photos of prominent people in the organization history, this would be a good way to protect the image for posterity.
Their similar initiative for other places. Former Ottawan Norma O'Toole, who suggested this post, mentions "Vancouver Then and Now" - Vintage photographs of Vancouver and surrounding suburb cities, throughout every era and every subject.Website: http://www.flickr.com/photos/entheos_fog... or https://www.facebook.com/VancouverThen/info
