I'm testing what happens if I'm sending an email to the user@flink list without being subscribed.
On the dev@ list, moderators get an email in that case. I have the suspicion that you can post on the user@ list without subscribing first. We have often users that ask a question, we give an initial response but never hear back from them. Maybe they are just not subscribed. If that's the case, I'll talk to the ASF to see what we can do.
