Connecting to Polyvore

Hello, I’m wondering if anyone has every had trouble linking their blog to polyvore. I am trying to be able to upload sets that I created on polyvore. It is asking me for my wordpress adress and password. Andy everytime i give my address it says my site does not exist!I have been advised never to give out my wordpress password either so I am at a loss but I see a million fashion blogs using polyvore is there some other connection? Sooo frustrating!!
