@themightymo The template file that handles this is bp-default/groups/single/home.php. See around line 44 – bp_group_status_message() creates the “to join this group…” message for private groups. If you want to customize the way that you are redirected, you should start here.

It’s strange, though – BP 1.2.4.1 should do what you are suggesting out of the box. Could there be a plugin conflict? Or an issue with a custom theme that you’ve built?
