Should I send the college additional info?

<p>Because I applied with art supplements, my REA application deadline was last week--pretty early. But now that I think of my application I think there were few points mentioning about me that I didn't do so, facts like:
I was founder/president of certain clubs but I only wrote "president",
Our school didn't have a CS course so I had to learn coding myself...</p>

<p>Stuff like that. Do you think these information could be skipped, or worth mentioning?
The thing is, as far as i know admission process doesn't begin until the early november deadline (w/o art supp) so I'm thinking about emailing the college to add this kind of info. What do you guys think?</p>
