I'm totally obsessed with Scrabble at the Pixie Pit. I believe it has a US$10 annual fee, but sooo worth it in my book! posted by crunchtopmuffin at 7:56 AM on April 4, 2008
The granddaddy of all PBM/PBEM games (excluding Chess, that's the great-granddaddy): Diplomacy.
Of course, I haven't played in a decade or so. It looks like the center of PBEM operations has shifted from The Diplomatic Pouch to Diplomatic Corp. posted by fings at 8:59 AM on April 4, 2008
There's a million of classic games at It's Your Turn. I played Pente there a bunch a few years ago. posted by aubilenon at 9:20 AM on April 4, 2008
