in the email template file, the code to write the lable in the email will look like:
<?php echo(str_replace("_"," ",$pkey)); ?>
change it to:
<?php echo(str_replace("_"," ",str_replace("Contact_Is_Group_", "", $pkey))); ?>
to remove that p0rtion of the field name in the email.
near the top of the email template file, you will see the following two lines:
$removeIncludes = array();
$removeIncludes[] = "Security";
change that to:
$removeIncludes = array();
$removeIncludes[] = "Security";
$removeIncludes[] = "submit";
this will remove the submit button from the email ass well.
