How does one get added to the SRV record and test out relaying?
Nevermind - just saw this: https://github.com/algorand/go-algorand-doc/blob/master/Relay%20Setup%20Guide.md - short answer is to send your host:port to firstname.lastname@example.org
Also, the corresponding documentation on the developer website is here: https://developer.algorand.org/docs/configure-your-node-relay
The plan is to consolidate the latest and greatest documentation on the developer website, so best to refer to that for the most up-to-date. We will be cleaning up the GitHub repo in the near future so that will be clear there as well.
