Thanks, Dan. I'm already on the Antora Zulip board as KLynn2019. Do I need permission to join the Asciidoctor Zulip board? I'm trying to log in with GitHub (same as with the Antora board) but I'm not able to get in.
(I realize this might be a Zulip issue, which isn't within your wheelhouse...)
Zulip uses GitHub for solely authentication, there are no extra permissions...or in other words, Zulip does not need to store your password, but instead trusts on GitHub for it.
If it's working for antora.zulipchat.com, you should be able to go to https://asciidoctor.zulipchat.com
, and use the "Log in with GitHub" button. If it doesn't, can you check in your GitHub account ("Settings"), that "Applications" shows "Zulip Cloud" under "Authorized OAuth Apps"?
