This should be it...
FILE:: Skin1/help/contactus.tpl
Looks for these types of code
Code:
<tr valign=middle>
<td class=FormButton>{$lng.lbl_first_name}</td>
<td>*</td>
<td nowrap>
<input type=text name=firstname size=32 maxlength=32 value="{$userinfo.firstname}">
{if $fillerror ne "" and $userinfo.firstname eq ""}<font class=Star><<</font>{/if}
</td>
</tr>
to remove the required check and the star it should look like this
Code:
<tr valign=middle>
<td class=FormButton>{$lng.lbl_first_name}</td>
<td></td>
<td nowrap>
<input type=text name=firstname size=32 maxlength=32 value="{$userinfo.firstname}">
</td>
</tr>
FILE:: include/help.php file
you will need to edit the following line
Code:
$fillerror = (empty($contact["firstname"]) || empty($contact["lastname"]) || empty($contact["email"]) || empty($contact["subject"]) || empty($contact["body"]));
Remove any that you do not want to require. Mine has already been modified so it may not look exactly like yours
