Setting up default groups in SharePoint 2010

In MOSS, you could use the “Set up groups” option within a site to create and assign the default Member, Owner, and Visitor groups.

In 2010, the “Set up groups” link does not appear.

The  “Set up Groups for this Site” page is hidden for SharePoint 2010.  You can still get to this page by url:

…/_layouts/permsetup.aspx
