The recent activity of a group user can be viewed by clicking on the "view profile" link on any post made by him/her, but I am seeing activity in groups that I have never even heard about, let alone become a member of, and the posts certainly belong to this group.
Maybe that could explain why some post have been "disappearing" from our group. I can see this happening not only on my profile but on other group user profiles as well. Comments? Suggestions?. (besides contacting Google I mean).
