Social Coop Wall -- 立て看
This thread is for off-topic posts. ("...a big notice board where people in your group can leave little messages.... Having a Wall thread encourages community interaction, and helps people who aren’t confident about posting new threads to take small steps and participate. And by specifically naming a space for off-topic content, you reduce the number of distracting or unnecessary threads posted to the group." - Loomio blog)
Because it is our Loomio group, the posts should probably be governance/admin related (otherwise, why not post on the Social.Coop timeline?).
