Hi
I noticed something fatal in my site now

i registered via facebook button that JFBC provided . everything is fine , i can even post comment to the articles ..
and then i logged out , created a new user ( didnt login via facebook ) and the user logged in but could post comment on articles as my facebook user

how is that even possible ? yes maybe coz its the same pc , but what if the user is opening my site in a public place like an internet cafe ?
please check this out asap for me
P.S just noticed i can still post comments even after i logout !!!
