I'm pretty sure that until recently all of the subgroups that I created within my group were listed on the main groups homepage.
Yup. Beta , first bullet. ?
I can click on the "Subgroups" menu item to see the subgroups that I'm a member of but can no longer see just a simple list of subgroups on the home page.
That page includes all subgroups, which isn't obvious if you happen to be a member of all of them. Or, I suppose, are a member of so many that the first list fills the visible portion of the page. ?
