Well, like I said - what do you mean by custom font? Some people want to have fonts on their site that aren't normally available on their users computer, and that's not good. If you just want to use Times, or something like that, just change the font-family on your Main CSS page for your style. It's suggested to add several fonts their, just as vbulletin does, ending with the type of font you are using (serif, sans-serif, etc).
