Each group on the 'Browse Groups' view should probably have a link/button to allow the user to join the group, to save them a click if they don't need to go to the group profile page to know they want to join.
I'm wondering if the 'Join Group' button should be present even when there isn't a signed in user. New visitors would gasp at a glance what you can do with groups on that page, and clicking on the button would prompt them to create a user account.
