Some of the earliest community groups on FLORA.org

Some of the earliest groups on Flora.org
Ask the Doctors, which was a real cool site managed by Rosaleen Dickson who I met from the Freenet. Involved in the publishing industry, she co-authored a book on HTML back in the early 1990's when it was such a new thing. She hosted pages on Canadian Books, and following the work she did with the doctors ran a "Ask Great Granny" site.
I believe Auto-Free Ottawa was the first community group I hosted, a group of people in the early 1990's envisioning an Ottawa that wasn't as dependent on the automobile.
Canadian Homeschool is the last of the original groups to be hosted on FLORA.org
Community Democratic Action
KC. Maclure Centre
MAI-not
Ottawa District Committee of Ontario Special Olympics
Peace and Environment Resource Centre -- still around, but has had their own domain name for quite some time.
Pednet was a mailing list hosted by Majordomo, and then moved to Mailman.
Visually Impaired was, I believe, information hosted by Charles Lapierre
Westend Family Cinema also obtained their own domain name quite some time ago.
As web access became easier for organizations it was far more common for groups to get their own domain names so that they could move their sites between hosts without anyone having to remember a new URL. There are many redirects still in the config files for such groups that were previously hosted on FLORA.org.
Coop Voisins (which Rina and I lived in from 1997 to 2003)
Digital Copyright Canada (specifically the DMCA forum)
There were other groups over the years, but not all of them still exist such as:
Car Free Living
Communities Before Cars Coalition
Coop Area Network (Networking between Coop Voisins and the Conservation Coop)
Cycle Challenge / Commuter Challenge
Economic Good
Famous 5
FTAA Ottawa
FVC (Fair Vote Canada) Ottawa
Food Action Ottawa (FAO)
Global Education Network
Global Issues Forum
Green Party (Ottawa region, back when the party was smaller)
International Association for Near Death Studies Ottawa)
Maclure Center
National Capital Runners Association
OPIRG Forestry group
Ottawa LETS
Ottawa River Bioregion Group
Ottawa Transit Riders Association
Ottawa Vegetarian Society
The Doorstep Alliance
After doing a bit of spring cleaning of some sites where I can no longer reach the managers, and who haven't updated the sites in years, there were only 4 sites remaining: two from close personal friends, and two community groups.
For the sites that I couldn't reach the managers I had set them to redirect to the most recent archived version of their sites on Archive.org. I made a mistake with the robots.txt file and they are temporarily unavailable, but I have sent a message to Archive.org in the hopes they can fix my mistake and restore the archive.
If there are any groups I've missed, please let me know in the comments. It has been a few years, and I've been looking at old Apache config files to be reminded of some of the organizations. I've not listed all the individuals (volunteers as well as individual election candidate websites from back when I hosted candidates during elections).
There have been many mailing lists over the years, but since this isn't something I'm planning on closing I won't get all nostalgic about them. I'm keeping the domain name and will be keeping the redirects active for any sites that have moved so bookmarks can be updated.
