Default font

I seen rushhourmadness's font...its like this...Comic Sans MS....

How do i set the default font for my whole forum? Or do I have to go in and change each setting manually?

 

Look under Admin CP, Styles & Templates, Main CSS, and change the appropriate Font Family settings.

 

so do i have to change each css setting or is there like a global setting i can just set...

 

You would probably have to change everything that's already specified in the default template. It shouldn't be hard, just copy and paste
