We’ve been looking for a plugin to display a custom message when users login to their dashboard, filled with HTML markup (hyperlinks, boldfacing, italics, etc.), and only editable by the admin.
This plugin does just that!
It would be nice to have a built-in HTML editor in the WP Admin back-end, but if you are savvy, a bit of hard coding (HTML) will get the job done.
Also, a built-in editor for the widget title would be nice, but this can be edited by visiting Plugins >> Dashboard Message >> Edit. Here, you can edit the following code to re-name the widget:
//Setup the widget
wp_add_dashboard_widget('dashboard-message', __('ENTER WIDGET NAME HERE -- DO NOT REMOVE SURROUNDING SINGLE QUOTES','dashboard-message'), 'displayMessageWidget');
