Dave,
The newsletter list is one-way, and so your response to it was sent through moderation.
I would *love* to have your help in getting the newsletter together. So far, it's just me, so there's no other communication channels, but the right one is probably the promo list - https://lists.centos.org/mailman/listinfo/centos-promo (copied)
This month, we have (so far) no reports from any of the SIGs, and that's where I've been working: Showing up for the SIG IRC meetings, and asking them for a report, as well as digging through their meeting minutes - https://www.centos.org/minutes/2018/ - looking for items of interest.
The next newsletter is scheduled to go out on July 2nd - I try to send newsletters on the first Tuesday of the month.
Welcome aboard!
