We found a fork of a page David had once prepared that listed many now lost sites. We will see if we can find and suitably index live sites that have other useful forks.
We remove and note here the one extant site from the roster he maintained.
david.dojo.fed.wiki
We pull the domain names from his page using the command line on the federation search host.
curl -s http://ward.dojo.fed.wiki/david-bovill-sites.json |\ jq -r '.story[]|select(.type=="roster").text' |\ grep '\.'
