Admin Message: is it working?

Forgive the dumb question, but exactly what does the Admin Message plugin do? I assumed that I would install the plugin and enter in the message (have done this), and it would show up on the various members' dashboards.

However, logging in as a generic member, I'm not seeing anything along those lines. I'm not sure if I'm just missing it or looking in the wrong place or expecting something different than what it actually does.

Happy to provide relevant login info in private communication.
