This looks great!

One quick thing I noticed it isn't showing the proper identicon for group admins. I believe the issue is that at the end of line 576 of group.php it reads data-username="<?php print $member->data->user_nicename; ?> but should read data-username="<?php print $u->user_nicename; ?>

@kycapstick the identicon bug should be fixed now.
