Something useful from 'junk' mails

With a high school junior in the house, we're receiving tons of 'junk' mails from colleges these days. They usually pile up on the desk until we have time to read and discard them.

Today, my wife found something useful, or rather something we have been anxtiously waiting for, an acceptance letter from RSI (Research Science Institute) summer camp at MIT (https://www.cee.org/rsi/) for our son. He is going back to the hot Boston for the summer after attending the PROMYS math summer camp (https://www.promys.org/) at Boston University last year.
