It appears that sovrnbitcoiner is down, and x21 (site maintainer) hasn't been seen in a few weeks so not sure it will ever be recoverable xD
It's basically a guide for using Tallycoin Connect & LND on a Raspiblitz to setup an LN Address to your own Tor only node.

I didn’t back it up, if the site ever comes back up I’ll setup my own ghost site and port it over.
If you need help in the mean time with setting it up, feel free to reach out.
It’s fairly straightforward if you already have both a Raspiblitz and running LND node.
