This WPMU plugin sets up a template system for new blogs. When a new blog is created it can have a template applied to it. These templates allow for these blog options to be set:
<ul>
<li>Blog options.(Privacy, Theme, Moderation, etc)</li>
<li>Extra posts to be created.</li>
<li>Extra pages to be created.</li>
<li>Extra links to be created.</li>
<li>Extra page categories to be created.</li>
</ul>
A default template can be created if all you are after is a single set of new blog defaults.

WPMU has great themes and plugins. Unfortunately, many, if not most, come with a nag notice that admins see about installing their notifications dashboard plugin. If you’ve bought one plugin for your site this is probably overkill. If you’re a developer you don’t need this on your client’s sites.
This is a simple plugin that removes the notice. The 1.3 version has been checked against WP 4.4 and recent WPMU plugins, but still should be backwards compatible with older versions of WPMU plugins.
Note: If you do decide to you install the WPMU notifications plugin, please deactivate this one first. Errors may occur if you don’t.

Remove WPMU Dashboard Install Nag

Works as advertised. Now, why a plugin should be needed for this is another question altogether, and installing and activating this plugin is no substitute for filing an RFE to either add a close button to those annoying nags or a switch to turn them off (and their pref doesn't always work, apparently).
Thanks for this!



Simple and to the point

This plugin removes the nag notice at the top of WPMU plugins and themes.
