Weeeeeell, that's because it's not a thing you "normally" do.
(Sorry though that I didn't explain totally the first time around). Basically, you send it to them "unofficially" with a short note asking them if they could please consider this additional item in your application, if not then no big deal, but if they would you would greatly appreciate it. It's not really official for any school, its just you using your brains and what you got in your profile. My guess is that for HBS unless it is something mega-major, they won't care (because everyone has been in Businessweek
), but for most other schools it might have some effects,
hope this helps my friend,
