How to make subfolders BOLD?
 

How do I make subfolders to appear bold on main page (forum index)?

I think it is just a template that evals each one. So, either open the template and make it bold there, or just add some css to make class ".subforumlist li.subforum" bold (never tested).

To find the template to modify, do this - vboptions > General Settings > Add Template Name in HTML Comments > set to Yes . Then go back to your page and view the source code and you will see the name of the template called around your part of the code. (Sometimes the template is the one mentioned at the very top of the page source.)

Very confusing answer. Which template do I open? It was so easy to do in 3.8, but in 4.0 there are *.css files all over the place, plus templates.
When I go to forumhome_subforumbit_post and add 'strong' html tag - nothing happens.

That is the correct template, however if you look at the css, you'll see that strong has been rewritten to inherit it's font-weight. So, just try span tags - <span style="font-weight:bold">stuff</span> Or just do it via CSS like I also suggested.
