Good plugin

I would like to give the first review of this plugin.

It works as expected. However, in my website, I only need or require the message to be displayed to current registered users and not to guest users as well.

As a future enhancement, it would be good to include the option to choose between to show the message only to registered users, only to guest users or both.

For the above reason, I ended up unstalling the plugin. However, as mentioned before, plugin does exactly what it says it currently does.
