Okay, I took a look at your forum. There doesn't seem to be an unread CSS class for the title, but there is a read class.
You can try this code with the logged status included.
body.logged-in .CardsListItem:not(.CardsListItem.read) .cardTitle .title::after {
content:"new";
margin-left:5px;
color:#fff;
font-size:65%;
background:#ff6000;
border-radius:4px;
padding:0 4px 1px 4px;
vertical-align:text-top
}
body.logged-out .CardsListItem:not(.CardsListItem.read) .cardTitle .title::after {
display: none;
}
However, you will also need this script

Thanks, @huseyinfiliz for that 😉
so that guests don't see “new” everywhere.
