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>

Take full control of your WordPress cron system. Advanced Cron Manager gives you complete visibility into every scheduled task running on your site — so you can find problems, fix them, and keep your site running smoothly.
WordPress relies on WP-Cron for critical background tasks: sending emails, publishing scheduled posts, running backups, syncing data, and more. But by default, you have zero visibility into what’s happening. Events fail silently, schedules pile up, and debugging is guesswork. Advanced Cron Manager changes that.
What you can do with the free version:
<ul>
<li>See every scheduled event — view all registered cron events with their hooks, arguments, schedules, and next execution times, all in one clean dashboard</li>
<li>Search and filter — quickly find the event you’re looking for, even on sites with hundreds of cron jobs</li>
<li>Run events manually — trigger any cron event on demand to test it or force an immediate execution</li>
<li>Pause and resume events — temporarily disable events without losing their configuration, perfect for troubleshooting</li>
<li>Add and remove events — create new cron events or unschedule ones you no longer need</li>
<li>Copy-paste PHP implementation — get ready-to-use code snippets for each event’s action hook and callback</li>
<li>Bulk actions — manage multiple events at once: remove, pause, or unpause in batch</li>
<li>Manage schedules — view, add, edit, and remove custom cron schedules (intervals)</li>
<li>Server Scheduler — disable WP-Cron’s default page-load triggering and get instructions for setting up a real server cron job for more reliable execution</li>
</ul>
<h4>Advanced Cron Manager PRO</h4>
The free version shows you what’s scheduled. PRO shows you what actually happened.
Without logging and diagnostics, cron issues are invisible until something breaks. PRO gives you the tools to monitor, debug, and optimize every cron job on your site.
<ul>
<li>Cron Logger — full execution history with timestamps and status for every event. Know exactly what ran, when it ran, and whether it succeeded or failed.</li>
<li>Performance Stats — execution time and peak memory usage tracked per event. Spot slow or resource-heavy cron jobs before they become a problem.</li>
<li>Error Catcher — automatically catches fatal errors thrown by cron callbacks and displays them in the log. No more silent failures.</li>
<li>Debug Tool — log custom data from inside your cron callbacks using <code>do_action('advanced-cron-manager/log')</code>. Get full visibility into what your code is doing during cron execution.</li>
<li>Event Rescheduling — change the next execution date and schedule of any event. Shift heavy tasks away from peak hours to balance server load.</li>
<li>Event Listeners — see every function and method hooked into each cron event. Understand exactly what code runs behind each hook.</li>
<li>Advanced Scheduling (Schyntax) — go beyond simple intervals. Schedule events for specific times like noon on the last day of the month, only on weekdays, every Tuesday and Friday, and more.</li>
</ul>
14-day money-back guarantee — no risk, no questions asked.

<h4>Good to know about WP-Cron</h4>
WordPress Cron is triggered by page visits, which means scheduled tasks may not run exactly on time on low-traffic sites. For precise timing, use the Server Scheduler feature to set up a real system cron job. Note: custom schedules added by this plugin are only available while the plugin is active. Events you create will continue to exist after deactivation.
<h4>Custom Development</h4>
BracketSpace — the company behind this plugin — provides <a href="https://bracketspace.com/custom-development/" rel="nofollow ugc">custom WordPress plugin development services</a>. We can build any custom plugin for you.

Thank you for this plugin. I'm liking it better than what I used to use. Excellent interface.
