Lucie, it's a bunch of woman who like to send snail mail still and do swaps. The one I belong to happens to be a bunch of woman who love Pioneer Woman. We do some stuff themed on PW, but mostly it's other stuff. For example this month I'm doing a scrapbooking/crafting supply swap. They've done a camping theme, color theme, and a ton of others I can't remember at the moment. We send birthday cards and postcards...and just whatever comes to mind.
It's something on Facebook and they call it "Happy Mail".
And Jody, I agree. Just write a note..How hard is it?
