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

Banner alerts are custom alerts to notify your website visitors of promotions, alerts, events, etc. These display at the top of the website until they are dismissed by the visitor. Any new visitor who has not been to the website will see these until they are dismissed.
Banner alerts are configured just like a post or page with support for title, content, and excerpt. The plugin settings allow you to define which parts of the alert to display and whether or not to link to the full post. You can run more than one alert at a time and activate or deactivate as needed.
This plugin is ideal for:
<ul>
<li>Important operational changes</li>
<li>Technical notices</li>
<li>Time-sensitive appeals for donation or action</li>
<li>Terms or agreement changes</li>
<li>Privacy notice acknowledgements</li>
<li>Service outages or maintenance messages</li>
<li>Special offers or promotions</li>
</ul>
