This hack moves Social Bookmarks to popupmenu like AddThis button.

Open SHOWTHREAD template and find
<!-- toolbar -->
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center" style="border-bottom-width:0px">
<tr>
<td class="tcat" width="100%">
<div class="smallfont">
<if condition="$show['firstunreadlink']">
<a href="$firstunread"><img class="inlineimg" src="$stylevar[imgdir_button]/firstnew.gif" alt="$vbphrase[view_first_unread]" border="0" /></a>
<a href="$firstunread"><strong>$vbphrase[view_first_unread]</strong></a>
</if>
&nbsp;
</div>
</td>
And below add:
<if condition="$bookmarksites">
<td class="vbmenu_control">
<a id="bookmark" href="#bookmark"><img src="$stylevar[imgdir_misc]/bookmarks.gif" border="0"</a>
<script type="text/javascript">
<!--
vbmenu_register("bookmark",true);
//-->
</script>

<div class="vbmenu_popup" id="bookmark_menu" style="display:none">
<table border="0" cellpadding="0" cellspacing="0" width=490pxalign="center">
<tr>
<td class="alt2" style="padding-top:0px"><div style="clear:both"></div><ul style="list-style-type:none; margin:0px; padding:0px">$bookmarksites</ul><div style="clear:both"></div></td>
</tr>
</table>
</td>
</if>
Then you must add some "bookmarks.gif" button picture in your forums [imgdir_misc] dir.
