Hi zotti,

The ML thing are atom and RSS. They certainly have a purpose for the reuglars on your blog. But you can remove them.
If your blog is <= 1.10.2 open ../blofs/skins/miami_blue/_main.php and remove:

<div class="bSideItem">
		<h3><img src="<?php echo $rsc_url ?>icons/feed-icon-16x16.gif" width="16" height="16" class="top" alt="" /> <?php echo T_('XML Feeds') ?></h3>
			<ul>
				<li>
					RSS 0.92:
					<a href="<?php $Blog->disp( 'rss_url', 'raw' ) ?>"><?php echo T_('Posts') ?></a>,
					<a href="<?php $Blog->disp( 'comments_rss_url', 'raw' ) ?>"><?php echo T_('Comments') ?></a>
				</li>
				<li>
					RSS 1.0:
					<a href="<?php $Blog->disp( 'rdf_url', 'raw' ) ?>"><?php echo T_('Posts') ?></a>,
					<a href="<?php $Blog->disp( 'comments_rdf_url', 'raw' ) ?>"><?php echo T_('Comments') ?></a>
				</li>
				<li>
					RSS 2.0:
					<a href="<?php $Blog->disp( 'rss2_url', 'raw' ) ?>"><?php echo T_('Posts') ?></a>,
					<a href="<?php $Blog->disp( 'comments_rss2_url', 'raw' ) ?>"><?php echo T_('Comments') ?></a>
				</li>
				<li>
					Atom:
					<a href="<?php $Blog->disp( 'atom_url', 'raw' ) ?>"><?php echo T_('Posts') ?></a>,
					<a href="<?php $Blog->disp( 'comments_atom_url', 'raw' ) ?>"><?php echo T_('Comments') ?></a>
				</li>
			</ul>
			<a href="http://webreference.fr/2006/08/30/rss_atom_xml" title="External - English"><?php echo T_('What is RSS?') ?></a>
	</div>

Good luck
