When I first tried it after seeing articles in The Washington Post about it, I thought, "OK, this is fun but not compelling...."
Then this thread appeared here.... Gee, thanks, Herdfan, you've now got me to where I'm doing it every day and actually today took the major step of bookmarking the site for quick and easy access..... LOL!!!
I rather like the idea that this is a once-a-day only deal, actually. Keeps me from obsessively spending hours playing word games!
SS: my mother, who has been gone since 2005, was a crossword fiend and enjoyed not just doing the ones in her local newspaper but also the ones in the various crossword puzzle books that were available, too. She would've loved this new challenge!
