Warning: This plugin is currently broken (at least for some sites) and I have no time to maintain it. I plan to solve all the issues from the support forum but I have no idea when that might happen (perhaps summer 2014). I am sorry and thank you for the understanding.
Provides a system for registration requests and their processing in multisite.
Blog administrator can place a shortcode <code>[murm-form]</code> on their blog, which will display a registration form. Visitors can then use this form to request registration. Such a request must be first moderated by the blog admin. If it is accepted, it’s passed on to the blog superadmin, who also has to approve it in order to pass. After approval the plugin creates given user accounts with subscriber rigths on the blog from which it was requested and sends login information to the user.
Per-blog settings
<ul>
<li>can be deactivated</li>
<li>notification via nag or e-mail on new requests</li>
<li>antispam (needs Akismet API key)</li>
<li>requests on the blog admin level can be automatically approved</li>
</ul>
Per-site settings
<ul>
<li>optional e-mail notifications</li>
<li>custom e-mail templates</li>
<li>blog administrators can be allowed to delete a request without notifying it’s author</li>
<li>requests on the network admin level can be automatically approved (this means that only blog administrators decide about their requests, if no error occures)</li>
</ul>
This plugin was developed for a small blog server (cca 30 blogs), so that superadmin would have control of newly created accounts (because some people were confused and got themselves unneccessary multiple user accounts).
Makes use of the <a href="https://wordpress.org/extend/plugins/wordpress-logging-service/" rel="ugc">WordPress Logging Service</a>.
In future there will be more options to modify default plugin behaviour.
<h3>Wishlist</h3>
Below are listed requests I know about and I’m going to process… eventually. Please be VERY patient.
<ul>
<li>“I have a request of asking for password on registration form. That way the user can pick out a password and have it automatically populated in the site user data.”</li>
<li>sidebar registration widget</li>
<li>attach custom admin message to user on request approval/denial</li>
<li>correct i18n, custom blog admin messages</li>
<li>custom shortcode css (error/ok) + information</li>
<li>save all settings as a single wp option</li>
<li>combine with pure-murm?</li>
<li>“I would like to add more fields like “country” in the Registration Page.”</li>
<li>custom new user default role</li>
<li>recaptcha on registration</li>
</ul>

Your wordpress website includes third party scripts and tools like website traffic analytics, ad banners counter by feedburner or some top lists. Google Tag Manager provides a comprehensive user interface to manage all these scripts (tags) and include them with a single plugin into your wordpress powered website.
This plugin includes both the javascript code to bring those tags into your site and the fall back iframe code to still provide functionality if javascript is disabled. Installation requires just two simple steps
<ol>
<li>Install the plugin.</li>
<li>Input the container ID in preferences</li>
</ol>
Instead of copy and pasting lots of script tags into you wordpress theme files or managing a couple of plugins for diverse services you can now serve this all from a single source – the Tag Manager. Tags are comfortably managed in the Google user interface, no need to further touch you wordpress installation.
Registration for Tag Manager (https://www.google.com/tagmanager/) is two simple steps before you receive the Container ID which is the only information the plugin requires to work properly. From now on, you have a couple of advantages:
<ul>
<li>a comprehensive overview of all tags you are using</li>
<li>tags can be deactivated in the Tag Manager</li>
<li>you can preview changes on your site before putting them live for your visitors</li>
<li>provide access to tags management for marketing staff – no code changes needed</li>
<li>use all the rules and macros to fine grained adjust tag usage</li>
</ul>
Besides management of tags you’ll notice better loading times of your website due to asynchonous loading of scripts.

Technical stuff:
WordPress only allows placement of tag-manager-code in the footer through wp_footer action hook. So if you want to place the code directly behind the body tag you have to edit your theme like this:
…
<body>
<?php global $wp_google_tag_manager;
if(is_object($wp_google_tag_manager) && is_a($wp_google_tag_manager,”WpGoogleTagManager”)){
$wp_google_tag_manager->output_manual();
} ?>
…

WP Google Tag Manager

Includes tags (code snippets) from Google Tag Manager into your site
