Hi!
You could edit the subtemplate-file for postings.
In version 2.2.1:
/themes/default/subtempletes/posting.inc.tpl.
Remove these lines:
<p>
<label for="hp" class="input">{#hp_marking#}</label>
<input id="hp" type="text" size="40" name="hp" value="{if $hp}{$hp}{/if}" maxlength="{$settings.hp_maxlength}" tabindex="3" /> <span class="xsmall">{#optional#}</span>
</p>
<p>
<label for="location" class="input">{#location_marking#}</label>
<input id="location" type="text" size="40" name="location" value="{if $location}{$location}{/if}" maxlength="{$settings.location_maxlength}" tabindex="4" /> <span class="xsmall">{#optional#}</span>
</p>
or (ver. 2.1.1)
/themes/default/subtempletes/posting.tpl.inc.
<tr>
<td><label for="hp" class="main">{#hp_marking#}</label></td><td><input id="hp" type="text" size="40" name="hp" value="{if $hp}{$hp}{/if}" maxlength="{$settings.hp_maxlength}" tabindex="3" /> <span class="xsmall">{#optional#}</span></td>
</tr>
<tr>
<td><label for="location" class="main">{#location_marking#}</label></td><td><input id="location" type="text" size="40" name="location" value="{if $location}{$location}{/if}" maxlength="{$settings.location_maxlength}" tabindex="4" /> <span class="xsmall">{#optional#}</span></td>
</tr>
