I'm am not real sure what you are asking. But, I know I had to turn of facebook connections (not really sure what its called) when I joined this forum.
I had no idea as to how it worked so I checked the box in my user "cp".
Check "options" in your user cp is what I am trying to say.
Hope that helps?
Edit: "User CP" then "facebook options". Its at the very bottom of the page.
I think its turned on as default. I turned mine off.
