This WPMU plugin creates under the Site Admin menu called “Bulk Create Blogs” where you can bulk create/add users to blogs.
To use the plugin you must create correctly formatted data. The plugin takes 
CSV formatted data where each row contains the following data.
<pre><code>domain, user_id, blog_title, blog_topic,
</code></pre>
Each of these fields is described below.
<ul>
<li>blog_domain (Mandatory): the domain name of the blog, this should only contain alphanumeric characters and be in all lowercase. If the blog domain is empty then users will be added to the site’s root blog.</li>
<li>user_name (Mandatory): the login id of the user to be added to the blog.</li>
<li>blog_title (Optional): the title of the blog.</li>
<li>blog_topic (Optional): the name of the blog topic that this blog will be categorised under. These topics are setup under the ‘Blog Topic Management’ tab. A blog_title must be chosen if you wish to set the blog topic. (Requires cets_blog_topics plugin.) </li>
</ul>
When each line is processed, if the blog named already exists then the user given 
is added to the blog. If the blog does not exist then it is created. If a blog title 
is not provided then the blog domain is used.
This plugin also provides support for LDAP user creation. If a user does not exist and 
the ldap_auth plugin is installed then it will attempt to create a new user.
At the moment this plugin only supports sites that use domain blog naming. Support for 
sub-directories is not planned but you could easily add it yourself.
The number of blogs that can be imported at a time is limited.

Additional Features

<ul>
<li>Create login redirects and logout redirects.</li>
<li>Allow/deny access to specific posts based on user roles.</li>
<li>Hide plugins on the Plugins -> Installed Plugins page from other users.</li>

</ul>
Shortcodes
The plugin provides a few utility shortcodes. These are mainly intended to help with creating login/logout redirects, but you can also use them in posts and pages.
<ul>
<li><code>[ame-wp-admin]</code> – URL of the WordPress dashboard (with a trailing slash).</li>
<li><code>[ame-home-url]</code> – Site URL. Usually, this is the same as the URL in the “Site Address” field in Settings -> General.</li>
<li><code>[ame-user-info field="..."]</code> – Information about the logged-in user. Parameters:
<ul>
<li><code>field</code> – The part of user profile to display. Supported fields include: <code>ID</code>, <code>user_login</code>, <code>display_name</code>, <code>locale</code>, <code>user_nicename</code>, <code>user_url</code>, and so on.</li>
<li><code>placeholder</code> – Optional. Text that will be shown if the visitor is not logged in.</li>
<li><code>encoding</code> – Optional. How to encode or escape the output. This is useful if you want to use the shortcode in your own HTML or JS code. Supported values: <code>auto</code> (default), <code>html</code>, <code>attr</code>, <code>js</code>, <code>none</code>.</li>
</ul>
</li>
</ul>
Notes
<ul>
<li>If you delete any of the default menus they will reappear after saving. This is by design. To get rid of a menu for good, either hide it or change it’s access permissions.</li>
<li>In the free version, it’s not possible to give a role access to a menu item that it couldn’t see before. You can only restrict menu access further.</li>
<li>In case of emergency, you can reset the menu configuration back to the default by going to http://example.com/wp-admin/?reset_admin_menu=1 (replace example.com with your site URL). You must be logged in as an Administrator to do this.</li>
</ul>

Admin Menu Editor

Does just what it says it does. Instantly.

Perfect

I've been a user of Admin Menu Editor and the Pro version for a while now. WordPress backend can get a little messy very easily, so this plugin comes to the rescue, and it does it well.

I wish all the features were free, but the devs need to pay the bills as well :-)

Best option


It allows you to move existing items on the left side menu around and change their icons.


Not Bad, simple to use


Essential for taming the admin menu, due to all the stupid ideas other developers have for their menus!


Essential
