Your website has:
font-family: “CronosPro”,“Courier New”,“Georgia”,serif;
You have a modern san-serif font (cronos pro), a fixed width font (courier new), a serif font (georgia), then a generic serif font.
I find this selection extremely odd. You are mixing sans-serif, fixed width and serif fonts all together. Viewing the forums in courier new is quite an experience.
Perhaps something like:
font-family: CronosPro,“Droid Sans”,Arial,Helvetica,sans-serif;
would be better.
