Andrew Smith is the admin for the group. As an admin he can enter whether someone needs to be an admin, moderator or simply member to be able to create documents. He can also enter whether someone is an member, a moderator or a fellow admin.
To check on any of these settings, he should go to the group and check the tabs available. One of them should be the admin tag. He can see settings for documents under admin > docs, and for members under amin > members.
So please get in touch with Andrew about this.
