окей, а как вот такой вариант:
// When a generated page (in PHP, Perl or something else)
// need add to each post (DIV, TABLE, TR, TD): onmouseover="qq.Nick='user nick'"
// Exsample for PHP: echo '<tr class="bugnote" id="'.$postId.'" onmouseover="qq.Nick=\''.$userNick.'\'">';
var qq = {
// QuickQuote Settings
LinkShowTime : 3000,
LinkId : 'quickQuote',
LinkStyle : 'z-index:1000; cursor:pointer; position:absolute; visibility:hidden',
LinkText : '<b>Цитировать</b>',
TextAreaId : 'bugnote_text', // id or name
// <--------------------
Link : '', TextArea : '', Text : '', Nick : '', TimerId : '',

// <--------------------
Осталось только разобраться с прокруткой в textarea.
