But I don't have a font called "Use common sense".
I was kidding.
I just need to type in whatever font I have in bytafont?
Good question i never pondered where these themes pull their fonts from.
I dont think bytafont has anything to do with it since sometimes these themes come with fonts i never downloaded..
Try and find a font folder/file in your theme. Perhaps you will need to download the font file you want from the internet as well.
Hopefully some modder will come along and clear this up for you because i am also curious now.
