Yes @End3rr is correct you will need to use firebug to select all the items you want to change and modify them in the style.css

you can change font and font-style in css file in the entry section. You can choose whether you want to change event title or its description.

hi chris. thank you 4 your work, i notice that you are very clever in answering about troubleshooting. good job! i'm very happy to have choosen this theme.

i've already seen what you said....but i didn't mean that thing... i don't wnat to change orbitron, i like so much it as main font! i want to change the posts-content's font, that is also the same of the widget's content, like archives or recents posts. it seems to be helvetica or trebuchet at this moment i think (but i'm not expert in fonts :) )
i managed to change posts-titles' font and widgets-titles' font (i moved to orbitron also there), but i didn't find the part of the code for posts description and widgets content.

in the WordPress admin

appearance ->theme options -> google fonts

HI FOLKS!
TNX FOR THIS GREAT THEME!

1 QUESTION: HOW I CAN CHANGE THE MAIN FONT? I MEAN THE FONT OF EVERY PART THAT IS NOT ORBITRON. I DID THIS STUFF ON WIDGET'S TITLE AND POST TITLES, BUT I CAN'T MANAGE IT FOR POSTS DESCRIPTIONS AND WIDGETS LINKS AS MONTHLY ARCHIVES ETC!
