Fonts
Here are a few different fonts I use in my themes I've made them into images so you can see them (font text test is in that font)

Mosh pitfont text test
francinemk font text test
bell bottom laser font text test
times new roman font text testNow I've put the font name underneath the image, but unless you have the font installed you will possibly see them all as times new roman
the bottom one is times new roman
To change font face in CSS its fairly easy if you want it all over
body {font-family: times new roman;} that will change font everywhere
In certain parts say page title h1#page_owner_title {font-family: francinemk;} that will make your page title the one font and everywhere else a different one
Remember only you will see the font if its different to the "standard" windows fonts (could you see the fonts above? )
So and here's a tip as there are a few windows fonts get one close to what you have already say I used bell bottom lazer as my main all over font
body {font-family: bellbottomlazer;} you can't see it, the one closest to it is comic sans so if I do this
body {font-family: bellbottomlazer, Comic Sans MS} then you will see comic sans
It works this way your computer sees the first one on the list it recognizes ,it knows comic sans so it goes "Yay I know that one I'll show the font as that one"
Oh and don't forget some fonts come up bigger than others I've made those all the same size so you can see them but both francinemk and Mosh Pit are small sized fonts
the times new roman is font-size:30px those are something like 40px.
Others are BIG I used one once called brandegoris even on size 12 it came out huge had to stop using it the font size of the actual font was messing my page alignment up
Just thought I'd throw this in seeing as folks were asking :-D
