I like the Dashboard.gif layout much better than your current page layout. The sign in/login gif is pretty good looking and I wouldn't change that to much. And like lab0rat said, Your colors should be brighter since this will be a social network for families.
All in all your site looks pretty good.
Good Luck

1. I like the purple horiz. line, but not the black header. Think I would use a darker blue, perhaps Navy with the white text. YOu have pleanty of room in the header to add a graphic or add a sub-title. Perhaps put the shadowy figures in your home page in, in the header.
Very Simple Design As i see you just Create one page , So i Can't say much about your site , First Place every necessary Thing on your site and after that let us review it :-) I'm sure you're Still working on it
