I would like to display the number of logged users (users online plugin) on the site only for logged users (my all members from trust 0-4).
But I don’t know how to disable this plugin on the site for guest ?
Why is there no such thing as a user group or trust level (-1 ? ) for not registered - not logged in/guest users?
How can I put it in the code?

Did you try changing the “whos online display public” setting?

Edit: Scratch this, see David’s post above. I didn’t realize a setting existed!

~~The simplest way would be to hide it using CSS, we add the anon class to the html tag when someone isn’t logged in.~~
```css
.anon #whos-online {
display: none;
}
```

Because we don’t know who they are, so we couldn’t effectively put them into a group.

Okay, thanks!
I’ll check it out right away, but I already have a question.
Why can’t I define a user group as not logged in? Other forums allow this. I mean, they give them permissions (like ipb, mybb, Vbull)
What if I want to write my own plugin that only activates for anonymous users? Is it enough for me to have a css class or something else?

oh I guess I see what you’re saying, this really isn’t a group though is it? A group has members. This would just be anyone who isn’t logged in. It’s kind of the lack of a group.
Are there other permissions you want to grant to anonymous users other than hiding whos online?

```plaintext
currentUser
```
You may need it in the plugin.

Yeah, there’s a lot of it. I would like for example the icons from the flag component ([Trust-Level Avatar Flair](https://meta.discourse.org/t/trust-level-avatar-flair/82656)) to appear only when users logged in.

You can target the anon class to hide pretty much anything from anonymous users.

So do I understand that a command is enough, or do I have to add some parameters?
```
const currentUser = this.currentUser;
if (!currentUser) {
return;
}
```

Yes, I think that’s enough.

Do I need to edit the plugin and rebuild the forum to make such a simple change or can I do it from the admin panel in the head or footer section. Is it possible?
