Multisite Directory provides a customizable Network-wide site directory for WordPress Multisite installations. You can categorize subsites in your Network, add full-length descriptions and featured images to them, and more. Theme developers can customize the look and feel of the site directory using all the tools they’re already familiar with. Blog authors can use a highly-configurable shortcode (<code>[site-directory]</code>) to display the directory anywhere shortcodes are supported.
Each time a new site or blog is added to your Network, a corresponding entry in the site directory is added, too. The directory is managed from the Network’s main site, but most changes to the subsites (other blogs) automatically update the directory. Many parts of a given site’s appearance in the directory can be modified without affecting the site itself. This means a Super Admin can use a custom site logo, tagline, and so on in the directory itself, without changing the site’s actual logo, tagline, and so on. Additional options in the Network Settings → Network Directory section allows Super Admins to tweak the bells and whisltes, such as keeping Directory Entry titles in sync with Site Name changes.
Site directory entries are implemented as a hierarchical custom post type in the main site. These pages can be categorized with a custom <code>subsite_category</code> taxonomy. We’ve found that this combination allows maximum flexibility while providing the tightest integration with existing WordPress core features. As a result, no new tables are added to your install, and no side effects are introduced. It Just Works.(TM)
Quickstart guide
After <a href="https://wordpress.org/plugins/multisite-directory/installation/" rel="ugc">installing</a> the plugin, you’ll want to:
<ol>
<li>As a Super Admin, go to My Sites → Network Admin → Sites. Notice the new “Categories” link on the sidebar.</li>
<li>Create some categories! If the category relates to a location (maybe it’s a site for a regional chapter of your organization?), be sure to click the map to geotag it.</li>
<li>Click on “Directory,” immediately above “Categories.” These pages are the individual directory entries, not the blogs. Categorize these pages as you would regular WordPress Pages to organize your Site Directory.</li>
<li>Go to any site’s Appearance → Widgets screen, and add a “Network Directory Widget” to a widget area.</li>
<li>If you’ve geotagged some of your Site Categories, choose “Display as map” from the widget options. (Otherwise, leave it on “Display as list.”)</li>
<li>Click Save, view your blog, and enjoy your new Site Directory!</li>
</ol>
Check out the <a href="https://wordpress.org/plugins/multisite-directory/screenshots/" rel="ugc">Screenshots</a> for a few examples.

A <a href="https://codex.wordpress.org/Create_A_Network" rel="nofollow ugc">Multisite</a> Network plugin.
Ever signup a user account, delete it, and try to signup up the same username again?
Ever try to support a new user who created a username, but entered the wrong email address and so can’t activate, and can’t signup with the same username?
Ever wanted to signup a bunch of users with phony emails so users without email could start blogging right away?
I have, so I made a plugin to help me.
WP Network Multisite “mu-plugin” for user activation key removal or approval.
See Network–>Users–>”User Activation Keys” to delete activation keys – to allow immediate (re)signup of users who otherwise get the “try again in two days” message.
Also, users waiting to be activated (or can’t because the email with the generated activation link is “gone”) can be approved manually.

User Activation Keys

This plugin saved me time to delete activation key directly in the database. It's much more easier to manage users in Multisite using this plugin. Thanks for the dev!



Must Have Plugin for Multisite

Works fine :)
