220	<p>If you have installed the single-blog version of WordPress before, please note that the WordPress µ installer is different and trying to create the configuration file wp-config.php youself may result in a broken site. It's much easier to use this installer to get the job done.</p>

226	<li>An empty MySQL database.Tables are prefixed with <code>wp_</code> which may conflict with an existing WordPress install.</li>
227	<li> Wildcard dns records if you're going to use the virtual host functionality. Check the <a href='http://trac.mu.wordpress.org/browser/trunk/README.txt'>README</a> for further details.</li>

474	<p>You can <a href='wp-login.php'>log in</a> using the username "admin" and password <?php echo $pass; ?></p>
475	<h3>Directory Permissions</h3>
476	<p>Please remember to reset the permissions on the following directories:
477	<ul>
478	<?php
479	reset( $dirs );
480	foreach( (array) $dirs as $dir ) {
481	echo "<li>$dir</li>";
482	}
483	?>
484	</ul>
485	</p>
486	<p>You can probably use the following command to fix the permissions but check with your host if it doubt:
487	<br /><code>chmod 755
488	<?php
489	reset( $dirs );
490	foreach( (array) $dirs as $dir ) {
491	echo "$dir ";

510	<h1>No-www</h1>
511	<p>WordPress µ strips the string "www" from the URLs of sites using this software. It is still possible to visit your site using the "www" prefix with an address like <em><?php echo $_POST[ 'basedomain' ] ?></em> but any links will not have the "www" prefix. They will instead point at <?php echo $nowww ?>.</p>
512	<p>The preferred method of hosting blogs is without the "www" prefix as it's more compact and simple.</p>
