If you downloaded Clubs Module (after June 8,2011), please ignore this... I have already applied in all versions.
If you already installed Clubs Module (before June 8, 2011), this is a tutorial on how to add hyperlink code.

BxClubsTemplate.php

Find this:

    function blockFields (&$aDataEntry) {
        $sRet = '<table class="bx_clubs_fields">';
        bx_clubs_import ('FormAdd');        
        $oForm = new BxClubsFormAdd ($GLOBALS['oBxClubsModule'], $_COOKIE['memberID']);
        foreach ($oForm->aInputs as $k => $a) {
            if (!isset($a['display']) || !$aDataEntry[$k]) continue;
            $sRet .= '<tr><td class="bx_clubs_field_name" valign="top">' . $a['caption'] . '<td><td class="bx_clubs_field_value">';
            if (is_string($a['display']) && is_callable(array($this, $a['display'])))
                $sRet .= call_user_func_array(array($this, $a['display']), array($aDataEntry[$k]));
            else if (0 == strcasecmp($k, 'country'))
                $sRet .= _t($GLOBALS['aPreValues']['Country'][$aDataEntry[$k]]['LKey']);


Below that, add this:

            else if ($a['name'] == 'url')
		$sRet .= "<a target=_blank href='".((substr($aDataEntry[$k],0,3)=="www") ? "http://".$aDataEntry[$k] : $aDataEntry[$k])."'>".$aDataEntry[$k]."</a>";
			
		
Example:

    function blockFields (&$aDataEntry) {
        $sRet = '<table class="bx_clubs_fields">';
        bx_clubs_import ('FormAdd');        
        $oForm = new BxClubsFormAdd ($GLOBALS['oBxClubsModule'], $_COOKIE['memberID']);
        foreach ($oForm->aInputs as $k => $a) {
            if (!isset($a['display']) || !$aDataEntry[$k]) continue;
            $sRet .= '<tr><td class="bx_clubs_field_name" valign="top">' . $a['caption'] . '<td><td class="bx_clubs_field_value">';
            if (is_string($a['display']) && is_callable(array($this, $a['display'])))
                $sRet .= call_user_func_array(array($this, $a['display']), array($aDataEntry[$k]));
            else if (0 == strcasecmp($k, 'country'))
                $sRet .= _t($GLOBALS['aPreValues']['Country'][$aDataEntry[$k]]['LKey']);
            else if ($a['name'] == 'url')
		$sRet .= "<a target=_blank href='".((substr($aDataEntry[$k],0,3)=="www") ? "http://".$aDataEntry[$k] : $aDataEntry[$k])."'>".$aDataEntry[$k]."</a>";
            else
                $sRet .= $aDataEntry[$k];
            $sRet .= '<td></tr>';
        }
        $sRet .= '</table>';
        return $sRet;
    }
}
