The archives of the project chat are public, so you can view the conversations without needing an account or having to sign in. Click the "Access without an account (Beta)" button on https://asciidoctor.zulipchat.com to enter the chat as a guest. If you wish to post, you will need to create an account and sign in.
There are various reasons why we're making this switch. First and foremost, Zulip (https://zulip.com) has proven to be a very effective communication tool for this community. Zulip combines the immediacy of real-time chat with an email threading model. We've been using it for over and year now. In that time, Zulip has been able to accommodate all the discussions we've had without any trouble. The discussions can be partitioned into streams, and the moderators have the ability to move topics and posts around, all of which helps keep the information more organized. The majority of members seem to be happy with it, and that exceeds our expectations.
In contrast, managing this list continues to be more and more of a burden for me. To ward off spam and abuse, I've had to switch to approving every new member, which is a tedious process and task. And, for some reason, even my own replies are rejected. I'm just fed up with it.
Having this list in use also splits the conversation across yet another channel, making it hard for people to find the information they need. We want to route these conversations to the chat and also keep such conversations out of the issue tracker. That leaves only the documentation and the project chat where users have to look to find information about how to use the software. It's a much more manageable situation.
