no change, Claimed notification still went to operator only. (it looked like it should have worked though ?)
Now that makes no sense.
$u->{email} is the Operator's email address.
$t->{email} is the email address for the ticket (belongs to the customer).
How did you make the edits? On your hard drive, then upload? (best) Or did you edit via FTP? (not so good)
Look and make sure the edits were accepted into the file.
