Hi. New WP user, building my first website. I'm trying to embed different forums into different areas of a casual use text based game. I'm sure the first two questions I have are simple, so please bear with me.

1. How do I get the icon that you can see in the attached picture to show at the top of my forum pages. I'm trying to avoid having a singular forum home (which I've been able to do). I've put the forums in the way I intended, with a menu option leading to the forum page directly. Creating topics is working fine and I'm really please with it.  The problem I'm running into is that when I open the topic to read it, there's no easy navigation back to the forum.

2. The second question is that at the top of the forum page it shows the Category Header. Is there a way to have that not show? I'd really rather have it not show. I've been able to get all the other things on the page removed, but that one seems to be harder (maybe impossible?) to remove.
