Shadow,
PHPFox is best in my opinion because if you want to use Facebook, then you will never
get good script. you can get the script CLONE from Scriptmafia.org but you need coder to fix the errors. Now i hope you understand. THANKS !!

1) PHPFox
2) Facebook Clone (Which needs Coder)

Regards.
Thanks bro,but i love that facebook clone,i have installed it,but it has Profile Image upload bug ,thats the prob. only
