Missing Set Up Groups page in SharePoint 2010

I discovered today that SharePoint 2010 gives you a nice new way to set the associated members group, but in doing so has hidden the "Set up Groups for this Site" page after initial site creation.

First the members group: This experience is actually much better. Most end users I have talked to are only concerned with which group is the default selection in the "Add users to a SharePoint group" dropdown on the "Add Users" page. A lot of them had trouble with the complexity of having to go to the "set up groups" page for this as it is definitely not the intuitive place to go. SharePoint 2010 has made this much easier. You simply navigate to the group you want as default and select Settings->Make Default Group.

For some reason though, the SharePoint team decided that the addition of this option would allow them to hide the "Set up Groups for this Site" page. You are shown it when you first create a site (if you select unique permissions) but seemingly can't go back after the fact. This can be a problem when you need to discover which group is the associated owners group or change it to a different group.

Luckily you can still get to this page by url: /_layouts/permsetup.aspx
