De hecho abdon, ese código no hace lo que el quiere.... esté es el código final y terminado:
Código:
{$ignore_bit}
<table border="0" cellspacing="{$theme['borderwidth']}" cellpadding="{$theme['tablespace']}" class="tborder" style="{$post_extra_style} {$post_visibility}" id="post_{$post['pid']}">

        </table>
    </td>
</tr>{$post['thxdsp_inline']}
</table>{$post['thxdsp_outline']}

Te explico, el quiere que el fieldset más al imagen esten debajo del avatar...
Fallo mio que puse el fieldset más abajo de donde era, pero ya edité el código.
Debería de poderse, pon la plantilla con los cambias ya hechos Wink
Aqui esta:

Ya empiezo a entender, se va a encerrar en social sites en un fieldset?
Reemplaza todo por esto
Código:
{$lang->postbit_posts} {$post['postnum']}<br />
    {$lang->postbit_joined} {$post['userregdate']}
    {$post['replink']}{$post['warninglevel']}
<fieldset><legend align=center>Perfiles</legend>
{socialsites}
</fieldset>

Avisa si te funcionó Wink xD
Bien pero combinada la plantilla del postbit:

Código PHP:
{$ignore_bit}
<
table border="0" cellspacing="{$theme['borderwidth']}cellpadding="{$theme['tablespace']}class="tborder" style="{$post_extra_style} {$post_visibility}id="post_{$post['pid']}">
    <
tr>
        <
td class="{$altbg}width="15%" valign="top" style="white-space: nowrap; text-align: center;"><a name="pid{$post['pid']}id="pid{$post['pid']}"></a>
        <
strong><span class="largetext">{$post['profilelink']}</span></strong> {$post['onlinestatus']}<br />
        <
span class="smalltext">
            {
$post['usertitle']}<br />
            {
$post['userstars']}
      {
$post['useravatar']}<br />          
  <
fieldset><legend align="center">{$post['groupimage']}</legend>
        
Pais:<img src="images/flags/{$post['fid8']}.gif" border="0" alt="{$post['fid**']}/><br />
                {
$post['user_details']}
            </
fieldset>
        </
span>
    </
td>
    <
td class="{$altbg}valign="top">
        <
table width="100%">
            <
tr><td>{$post['posturl']}<span class="smalltext"><strong>{$post['icon']}{$post['subject']} {$post['subject_extra']}</strong></span>
            <
br />
            <
div id="pid_{$post['pid']}style="padding: 5px 0 5px 0;">
                {
$post['message']}
            </
div>
            {
$post['attachments']}
            {
$post['signature']}
            <
div style="text-align: right; vertical-align: bottom;" id="post_meta_{$post['pid']}">
                <
div id="edited_by_{$post['pid']}">{$post['editedmsg']}</div>
                {
$post['iplogged']}
            </
div>
        </
td></tr>
    </
table>
</
td>
</
tr>
<
tr>
    <
td class="{$altbg}style="white-space: nowrap; text-align: center; vertical-align: middle;"><span class="smalltext">{$post['postdate']} {$post['posttime']}</span></td>
    <
td class="{$altbg}style="vertical-align: middle;">
        <
table width="100%" border="0" cellpadding="0" cellspacing="0">
            <
tr valign="bottom">
                <
td align="left" ><span class="smalltext">{$post['button_email']}{$post['button_pm']}{$post['button_www']}{$post['button_find']}{$post['button_rep']}</span></td>
                <
td align="right">{$post['button_edit']}{$post['button_quickdelete']}{$post['button_quote']}{$post['thanks']}{$post['button_multiquote']}{$post['button_report']}{$post['returntotop']}{$post['button_warn']}{$post['button_reply_pm']}{$post['button_replyall_pm']}{$post['button_forward_pm']}{$post['button_delete_pm']}</td>
            </
tr>
        </
table>
    </
td>
</
tr>{$post['thxdsp_inline']}
</
table>{$post['thxdsp_outline']} 

Mas la de postbit_author_user

Código PHP:
{$lang->postbit_posts} {$post['postnum']}<br />
    {
$lang->postbit_joined} {$post['userregdate']}
    {
$post['replink']}{$post['warninglevel']}
<
fieldset><legend align=center>Perfiles</legend>
{
socialsites}
</
fieldset

Si queda el cuadro pero se sale de margen el texto y lo de agracecimientos queda abajo de socialsites, pueden detallarlo mejor si miran aqui:
http://vortexforum.byethost9.com/showthread.php?tid=187
Haremos lo siguiente... reemplaza todo el postbit_author_user por esto:
Código:
{$lang->postbit_posts} {$post['postnum']}<br />
{$lang->postbit_joined} {$post['userregdate']}
{$post['replink']}{$post['warninglevel']}
y luego reemplaza todo tu postbit_classic por esto:
Código:
{$ignore_bit}
<table border="0" cellspacing="{$theme['borderwidth']}" cellpadding="{$theme['tablespace']}" class="tborder" style="{$post_extra_style} {$post_visibility}" id="post_{$post['pid']}">
    <tr>
        <td class="{$altbg}" width="15%" valign="top" style="white-space: nowrap; text-align: center;"><a name="pid{$post['pid']}" id="pid{$post['pid']}"></a>
        <strong><span class="largetext">{$post['profilelink']}</span></strong> {$post['onlinestatus']}<br />
        <span class="smalltext">
            {$post['usertitle']}<br />
            {$post['userstars']}
      {$post['useravatar']}<br />          
  <fieldset><legend align="center">{$post['groupimage']}</legend>
        Pais:<img src="images/flags/{$post['fid8']}.gif" border="0" alt="{$post['fid**']}" /><br />
                {$post['user_details']}
            </fieldset>
<br />

<fieldset><legend align=center>Perfiles</legend>
{socialsites}
</fieldset>
        </span>
    </td>
    <td class="{$altbg}" valign="top">
        <table width="100%">
            <tr><td>{$post['posturl']}<span class="smalltext"><strong>{$post['icon']}{$post['subject']} {$post['subject_extra']}</strong></span>
            <br />
            <div id="pid_{$post['pid']}" style="padding: 5px 0 5px 0;">
                {$post['message']}
            </div>
            {$post['attachments']}
            {$post['signature']}
            <div style="text-align: right; vertical-align: bottom;" id="post_meta_{$post['pid']}">
                <div id="edited_by_{$post['pid']}">{$post['editedmsg']}</div>
                {$post['iplogged']}
            </div>
        </td></tr>
    </table>
</td>
</tr>
<tr>
    <td class="{$altbg}" style="white-space: nowrap; text-align: center; vertical-align: middle;"><span class="smalltext">{$post['postdate']} {$post['posttime']}</span></td>
    <td class="{$altbg}" style="vertical-align: middle;">
        <table width="100%" border="0" cellpadding="0" cellspacing="0">
            <tr valign="bottom">
                <td align="left" ><span class="smalltext">{$post['button_email']}{$post['button_pm']}{$post['button_www']}{$post['button_find']}{$post['button_rep']}</span></td>
                <td align="right">{$post['button_edit']}{$post['button_quickdelete']}{$post['button_quote']}{$post['thanks']}{$post['button_multiquote']}{$post['button_report']}{$post['returntotop']}{$post['button_warn']}{$post['button_reply_pm']}{$post['button_replyall_pm']}{$post['button_forward_pm']}{$post['button_delete_pm']}</td>
            </tr>
        </table>
    </td>
</tr>{$post['thxdsp_inline']}
</table>{$post['thxdsp_outline']}

Ahi estoy 75% seguro de que funciona, avisa que sucede luego...
