*If you were a member before, JA manually joined all who were on the old site because many were having trouble. So if your adult groups don't show up or you cannot access them, message her or use the Feedback tab on the left of the page or the drop-down Home menu on mobile.
*If you were not, you must have your profile filled out, including year of birth, though that is not visible to others. Then use the Muggers drop-down menu and click on Join Adult Network.
