PMA has a Facebook page. https://www.facebook.com/groups/PeacockMilitary/
You can join by clicking on the URL above. You can contact all current members by emailing:
PeacockMilitary@groups.facebook.com
If you have tried to join and never heard back, it’s because of a requirement that an administrator approve all new members and the administrator (me) did not know to check for new membership requests. That has been changed and any member may now approve new member requests. You should be approved within a day or less.
My apologies to anyone who tried to register and never heard back.
