Why is it necessary to get approval to join this list?
For at least a year, new members are required to request approval to join this list. I want to explain why this step is necessary so people understand why I have enabled it.
I want to start by saying that I'm sorry this approval process is inconvenient. Nabble has a spam problem it refuses to deal with, and this is the only tool we have to combat it. Without this approval process, everyone on the list gets hit with a batch of spam several times a week, which turns subscribers away. It also requires effort on my part to go back and scrub those messages from the archive. It's easier for me to field new member requests than it is to clean up the spam posts. And since I've enabled this process, there has been no spam. So as long as we use Nabble, this is the process we must have.
I invite you to join our new community chat / forum at https://asciidoctor.zulipchat.com. It's showing promise that it could one day replace this mailing list and consolidate the discussions under one virtual roof.
