The person who set this up does not seem to be around Devuan... It would be nice to find out.
Then, the idea would be to help maintain the wiki as it is relevant to Devuan, and more specifically maintain the Devuan-specific information.
This (or other) .onion will allow people to access the devuan.org within the Tor network. In the first phase, it will simply offer a transparent proxy to devuan.org. In the future it could provide a Tor-specific entry-point.
