Updating UC application help?

I am a current high school senior in my second semester. I am concurrently enrolled and taking two classes at my local community college. However, in the fall when I was applying to UCs, I was not planning to take the two college classes, so I did not report them on my UC application. I was wondering what the process was to tell the campuses about my two additional classes? Online, the website tells me I can send an email, but how do I format it? Do I send it as an attachment? I am just not sure how to report it.

From the UC Website::::

Freshmen: If you change schools, add or drop a course, or fail to earn a C or better in a course after you submit your application, you must notify the UC Application Center by email or postal mail. Your correspondence must include your name, UC Application ID number and your signature (if you mail a letter), and will be available to all the campuses to which you applied.

If you receive an offer of admission, be sure to confirm with the campus admission office that they are aware of the deficient grade or schedule changes. Although you must notify the campus of these changes, we cannot guarantee that a campus can go back to review an application after correspondence has been received. Make sure to save a copy of your correspondence just in case.
