Want to learn a little something about words?
I signed up a while ago for a free email subscription to Daily Writing Tips and I find it both interesting and helpful. I've written the Daily Tipper a couple of times with questions or comments, and she has been very responsive.
I used to forward tips to my kids occasionally, but then my high schooler got her own subscription. She says that the tips have been startlingly timely -- sometimes a tip will have something to do with that day's schoolwork!
