splitting multiple tag results by author in tag.php

I’m using Query Multiple Taxonomies plugin on a site I’m developing for some friends. It works great when I use my standard tag.php sheet, however, the whole idea of the blog is that everything is split by the two authors into two columns – so author A’s posts appear in the left column and author B is in the right column.

So… when I use single_tag_title() in the following query it means that the query multiple taxonomies plugin doesn’t work properly

<?php $current_tag = single_tag_title ("", false);
query_posts(array(
'author_name'=>'Jenny',
'tag_slug__and'=>array($current_tag),
) );

while ( have_posts() ) : the_post() ?>

This is the only way I can think of to separate the tag results down into the author columns. But what then happens with the the Query Multiple Taxonomies plugin is the ‘add-term’ ‘remove-term’ aspect gets broken so that you can only add terms and then clear them, rather than dynamically adding and removing terms from the list – which is really how this needs to work!!!

I’m stuck on this one and would REALLY appreciate if someone has the answer as I want to give the site to my friends asap.

I’ve tried to find anything other than the single_tag_title() to use instead, but I’m stumped!
