WHO WRITES cards and letters these days? Me and a couple of other people. But maybe there will soon be more of us, because a writer named Mary Robinette Kowal has launched a project for February 2012 called The Month of Letters Challenge. The idea is to mail at least one item through the post every day. Okay, it’s the 2nd already, but we can make up for lost time, right? For details (you can sign up formally, or go it alone) check out www.maryrobinettekowal.com/journal/month-of-letters/ Thrill your friends with actual mail! Send them a letter, the sooner the better! Help the U.S. postal service amass some cash! (Remember, first-class now costs 45 cents.)
