Both my wife and I have joined the Picturesocial.
First it acknowledged both my wife and myself as being independent members but now all photos added by my wife are added to my photo's (I love the good comment but they are not my photo's) and my wife can't get into her page without my name coming up on the top right hand corner.
all comments from my wifes page are also credited to me
This is just a guess. Could the cookies in your web browser be telling the server at Picture Social (P.S.) who it thinks is on line? I've noticed that if I close P.S. on my browser to jump to another site, and then quit and shut down the computer. The next time I turn on the computer and open P.S., I'm already logged in. On the other hand, if I log out of P.S., and then shut down the computer, the next time I open P.S., it does not know who I am until I log in. My guess is your cookies are the culprit.
I suspect you are both using the same E-Mail Addy. All accounts are connected to the E-Mail you signed up on.
One of you should sign up with another E-mail to create separate accounts.
