Remember Xt3.com, the Catholic social networking site set up for the last World Youth Day?
If you haven't signed up, you really should!
For Lent they offer a cutesy calendar which provides a short verse for the day, links to the Mass readings (Ordinary Form only unfortunately) of the day, as well as a suggested 'Lenten Act' (today's was, 'In the midst of your day, stop and say three Hail Marys').
Oh and there is also a quite nicely challenging quiz on Lent, with a mix of the serious (Scripture, fasting rules, etc) and liturgical and devotional trivia. Mind you, if I recall correctly from last year, more than a few bishops got the answer to the question 'On which day is the chrism mass held' wrong (not that any of the answers they provided were actually options in the quiz!)...
