This plugin has been thoroughly tested and is fully compatible with WordPress 3.0x multisite or with WPMU 2.9.
This plugin was originally named YD WPMU Sitewide Options. The name has been changed with version 3.0 to match WordPress 3.0 vocabulary and concepts. Backwards compatibility with WordPress MU has been maintained.
<h4>Centralized management of your network-wide installed plugins!</h4>
This WordPress 3.0 multisite or WPMU plugin installs a new settings page where you can choose which blog or plugin settings you want to replicate site-wide or network-wide to all your children sites. 
Any change (update) to those settings (options) on the mother site admin pages can be automatically copied to all the sub-sites (blogs).
You can choose which settings to replicate, you can decide if changes of the settings on the main blog should be automatically replicated to all blogs.
You can replicate your settings as a “one-shot” process (for example when setting up new blogs or installing a new network-wide or site-wide plugin), 
or have the plugin maintain your settings in sync on all your blogs over time.
You can decide if chosen settings will be automatically “spread” to newly created blogs or not.
You can choose to manually spread the settings only when you decide to, and not to overwrite existing individual blog settings. 
This way, you can maintain specific settings on some blogs while keeping the ability to spread default settings to new blogs.
Since version 4.0.0, the plugin can now create and copy custom database tables used by some plugins, further widening the scope of plugins that can be made network-wide manageable.
Those techniques can be used to convert any standard WordPress plugin from standalone to a versatile multisite network-wide or sitewide WPMU plugin!
You can use your main blog as a template-blog for the creation of new sites in your network: the new sites can automatically adopt any or all settings of your main blog, 
activated plugins can also be copied, as well as the settings of each plugin. This is an alternative to other commercial or non-commercial new blog defaults / new blog template plugins for WPMU.
Many other creative uses are possible.
It efficiently makes for a centralized deployment of any plugin parameter on all your WPMU blogs: the main blog acts as a “master” when setting the site-wide option, while your child blogs replicate any change in the option over time like “slaves” (a rather typical master-slave replication pattern).
The plugin has its own admin options page (settings page).
It is fully internationalized.
Base package includes .pot file for translation of the interface, and English, French, Dutch and German versions.

Only some plugins that do not use either WordPress’ built-in options mechanism or some simple database tables to store their settings cannot be made network-wide with this plugin. 
However, the vast majority of state-of-the art third-party plugins use options and/or simple tables.

YD Network-wide Options

This plugin has been thoroughly tested and is fully compatible with WordPress 3.0x multisite or with WPMU 2.9.

The ‘Network Subsite User Registration’ (NSUR) plugin removes the WordPress Multisite restriction that registration is on the Network main site, subsite Administrators can now allow user registration for their site only.
WordPress Network (Multisite) installations by default only allow user registration for the whole Network, e.g. users can only register for the main site and not the other sites on the network. The ‘Network Subsite User Registration’ plugin allows local admins of sub-sites within the Network/Multisite the ability to enable user registration themselves for their site.
The role by default that a new user receives is ‘subscriber’, however, there is a setting which allows you to define a different initial role (per sub-site) that a user receives after registration.
@Developers – If you want to use your own template you can override the template used for the ../local-signup page by creating a template with the file ‘page-signup.php’ and add this to either the parent or child theme.

Network Subsite User Registration

This plug-in works great to handle a situation that Wordpress should just do out of the box.  I would be hard pressed to make multi-site usable without it.

So simple, but a huge time savings


Ideal for maintaining control over users.


Work as imagined

Allow the public to register user accounts on Subsites within a Network (MultiSite) installation.
