Hi, I am an admin for the Terror Britannia clan who has been trying to tidy up some old group announcements. I have been able to successfully delete most of them, but some I can't and it's pretty frustrating. When I try to delete them I get the message: "Moderating non-member posts in public group threads is not permitted." They were probably created before we set posts to be private, but all I want to do is remove them from our group announcements. Is there any way to make this happen? Pretty please? Thanks.
