Re: Replying to the list using the web site
What you describe having done is exactly correct. I am subscribed as "no email" but just changed to "all messages" prior to composing this response via the web. It may be that Groups.io uses an intelligent filter that doesn't e-mail your own messages composed via the web back to you.
I'll report back in a few minutes as to whether this one appears in my inbox as an email message.
The real art of conversation is not only to say the right thing in the right place but to leave unsaid the wrong thing at the tempting moment.
