You Can Create a message that will be shown to Logged in user.
A Similar one that will be shown to Guests
There is no such option here
please state your goal, or your problem in a more descriptive way.
perhaps you might want to use pockets plugin.
if you want to isolate messages logged in vs. non-logged in.
just write a plugin to check if logged in and add some css code to hide message.
I need to display a general message for everyone and I thought the messages feature is for that
But it isn't getting displayed for logged in users
that's odd. that is the default action.
maybe your theme template or a plugin conflicts.
