[question?]

I've changed the postbit ban, to not allow user group 6:

<if condition="($show['btu_canban']) AND ($post['usergroupid'] != 6)">

and only allowed admins to clear ALL bans:

<if condition="$show['btu_canban']">
    <div><label for="ao_btu"><input type="radio" name="do" id="ao_btu" value="btu_clear" />$vbphrase[btu_clear]</label></div>
    <if condition="$usergroupid == 6"><div><label for="ao_btua"><input type="radio" name="do" id="ao_btua" value="btu_clear_all" />$vbphrase[btu_clear_all]</label></div></if>
    <div><label for="ao_btuv"><input type="radio" name="do" id="ao_btuv" value="btu_view_all" />$vbphrase[btu_view_all]</label></div>
    </if>
