Single and couple join isn't the limit you know. Dolphin is very flexible. A new design is just a template away and menus are deletable. I used 6.1.4 to create a wonderful homepage not for people to be friends and not for cheating on their spouse. Couples are seen as couples clearly. It is important to get to see the flexiblity of Dolphin 6 fully before you can even make a comment saying it is a step backward. It clearly isn't.
