You want the users listed, just not linked? Just edit the FORUMHOME template to remove it (the red stuff):

<li>{vb:stylevar dirmark}<a class="username" href="{vb:link member, {vb:raw loggedin}}">{vb:raw loggedin.musername}</a>{vb:raw loggedin.invisiblemark}{vb:raw loggedin.buddymark}{vb:raw loggedin.comma}</li>

If you do a Search in Templates for class="username", you will find it in several places and you would need to remove it in each place you don't want it linked.

OR, add this to your additional.css:

a.username {
  pointer-events: none;
  cursor: default;
}
