I've noticed that several users are attempting to post messages to Spark's user / dev mailing lists using the Nabble web UI ( http://apache-spark-user-list.1001560.n3.nabble.com/). However, there are many posts in Nabble that are not posted to the Apache lists and are flagged with "This post has NOT been accepted by the mailing list yet." errors.
I suspect that the issue is that users are not completing the sign-up confirmation process ( http://apache-spark-user-list.1001560.n3.nabble.com/mailing_list/MailingListOptions.jtp?forum=1), which is preventing their emails from being accepted by the mailing list. I wanted to mention this issue to the Spark community to see whether there are any good solutions to address this. I have spoken to users who think that our mailing list is unresponsive / inactive because their un-posted messages haven't received any replies. - Josh
