OBS Server List... how to get on it?

[Bestalexmartin]

Let's say I ran a streaming service company that did the basic RTMP ingest. What would the criteria be to get on the list of servers in the streaming setup panel? I see there are at least a few that don't appear to have any options other than server and key so I'm wondering what are the requirements to be included on this list.

Thanks in advance for the attention.
