unset session array

[eluser]Dam1an[/eluser]
a) Why not carry this on in your other session thread
b) Have you read the user guide?
c) Where did you get the 'unset' function from? Cause it's not documented, and it's not in my copy of CI
d) unset_userdata takes a string, which is the key to the var to unset, or an array, not the variable itself
