This plug-in will only work on a Multisite running WordPress 3.9+.
This plug-in allows an Network Admin to create admin notices that appear on the top of all admin screens of the 
network’s sites. This notices are styled identically to the “normal” WordPress notices that you might see (WordPress 
updates, “post published” messages etc). Additionally each notice has a “dismiss” link which allows the user to 
instantly dismiss the notice.
Once a user dismisses a notice there will never again see that notice, on any of the network’s site.
Health Warning: The notice messages are considered HTML! A “small” inline tinyMCE editor will be used in a 
future update. But for the time being be aware that when you create/edit notices you are editing HTML (think WordPress 
‘text’ tab on the editor).
Before using the support forums, please read the FAQ. Thank you!

WordPress admin notices and dashboard notifications can quickly become overwhelming. Plugin alerts, theme warnings, update messages, and promotional notices often take up valuable space and disrupt your workflow. Disable Admin Notices gives you full control by letting you hide, remove, or disable admin notices across the entire dashboard.
You can hide all notifications, disable selected notices only, or move everything into a clean compact bar so messages no longer clutter your admin screen. The plugin also lets you disable plugin and theme update notifications, disable WordPress core update alerts, manage which items appear in the admin bar, and even block redirect URLs used by some plugins to show ads or promotional pages.
