To complement the [is_user_logged_in] shortcode I noticed a [is_user_logged_out] shortcode was missing from <a href="https://wordpress.org/extend/plugins/members/" rel="ugc">Members plugin</a>, soI decided to write an “extension plugin” to add it. Maybe this can be added to <a href="https://wordpress.org/extend/plugins/members/" rel="ugc">Members</a> itself one day?
The [is_user_logged_out] shortcode should be used to check if a user is currently logged out of the site. If not, the content will be hidden.
Example: 
[is_user_logged_out]This content is only shown to logged-out users.[/is_user_logged_out]
This shortcode has no parameters.
