BuddyMessageUX-Free is a BuddyPress plugin.
Default behavior for the buttons is to take you to your own profile – to compose and send messages from there. 
Why? Why not stay on the profile page you are viewing?
Fortunately, BuddyPress makes it easy to replace the functionality for those buttons. 
With this plugin you can stay on a profile page and send private or public messages to that member.
This plugin uses the default WordPress ‘thickbox’ code.
If you need… 
* the ability to style the overlay 
* adjust the javascript 
* or prefer the use of ajax

This plugin will enable the site administrator to easily create an admin message present on all pages. The admin has the option to let the user dismiss the message for the duration of his session.

Admin User Message

I love to use it when a website is migrated over to a new host and the DNS propagation may take a lot to be updated. Editors need to know they should stop publishing for a while :)



Useful

This does just what I want. Thanks for making it. :)
It's definitely better than https://wordpress.org/plugins/admin-screen-messages
You might want to also tag it as:
https://wordpress.org/plugins/tags/admin-message



Perfect

Add message to users of your site. Choose wheter they can dismiss it or not.
