This is a very simple hack. Some people prefer to show the * that indicates required fields after the label text, or to style it differently to the label text. This is how you can do both of those things.
Open sc_admin/include/contact.php
Change line 321 from this ...
if ($indicator_status == 1 && $data["required_status"] == 1) { $label = "* ".$label; }
... to this (all on one line) ...
if ($indicator_status == 1 && $data["required_status"] == 1) { $label = $label." <strong>*</strong>"; }
That will place the * after the label text, with a strong tag around it that you can use for styling. For example if you wanted the * to be red, add this to your CSS...
label strong { color: red; }
... that should do the job.
