Why does Forum Home display completely differently than all other pages?

[legion_diabolic]

I've just about had it with this retarded program. Why is there a template manager if pages are going to arbitrarily ignore whatever you enter for your style? Why does the forum home ignore the css i have specified when all the other forum pages display properly? Why are there so many undocumented instances of page elements arbitrarily using the css setting from OTHER page elements rather than being included in the styles manager? I have entered the css setting for every page element I have acces to through the style manager/template editor. My page, specifically my forum home page ARE NOT using the css I have specified so can someone please tell me WHERE this program is pulling the css from??? I HATE this program.
