GuruzLord Well the first part could be like
<script>
var authors = document.querySelectorAll("a[href*='/u/']");
for(i=0;i<authors.length;i++){
var span= document.createElement("span");
span.setAttribute("style", "background-color:orange");
span.innerHTML='Mem';
authors[i].appendChild(span);}
</script>
Copy code The rest you should be able to work out from that
