XF 1.5 Hide usernames from guests

[the]

I would like to hide usernames from guests.
I cannot find an add on to do this.

I did find this old post

https://xenforo.com/community/threads/hide-username.63831/

Is this still valid? Can I get some assistance with current syntax for 1.5 to mimic that thread? Maybe a better way to do that?

Thank you

You could use a conditional to achieve this.

I understand. I was hoping for some guidance on the above link (for 1.3 using conditional) in adapting to 1.5

I wasn't sure if I needed to change anything else given the version differences.

I'm glad to know the conditional statements are the way to go. Thank you
