In olden times, people used to send little rectangles of card when they went away using something called 'post'. These cards, which went in the post, were called 'postcards'. Your grandparents might remember them. If you want to communicate with home, or any else that matter and show them the epic stuff you're doing with Exile Medics, then this is the way to do it. Old school. Don't forget a pen to write with though!
