I actually just figured this out. The code you’re looking for is on line 241. Simply change this line:
$output_line = “‘ . $pst . ” . ‘(‘ . $ptopic_replies . ‘)’ . ‘ in ‘ . $pforum_name . ‘ by ‘ . $puser_name . ‘ on ‘ . $fmt_date . ‘
‘;
to
$output_line = “‘ . $pst . ‘‘ . ‘
‘;
I tested it, it should work.
