I also noted that you posted about shutting off email in another thread (that was erased as a duplicate)
To make the email field not required ... (note: if you did decide to allow customers to use the interface this would have to be turned back on. I am also unsure what shutting off email would do to the system) but its controlled in the
/include/class.ticket.php
circa line 1079
change the required from 1 to 0 on the line that looks like:
$fields = array('type'=>'email', 'required'=>1, 'error'=>'Email is required');
circa line 1166
change the required from 1 to 0 on the line that looks like:
$fields = array('type'=>'email', 'required'=>1, 'error'=>'Valid email required');
You would also have to go into your MySQL database into the ost_ticket table and change field email to allow null.
Good luck,
