Because everyone should know some Latin...

Per the Pope's instruction that all Catholics should know basic prayers in Latin, I dug up this website of Latin prayers. I didn't spend a ton of time looking at it, but it looks pretty complete, accurate, and non-heretical/schismatic (though so many Latin sites are, that I can't vouch for anything you might find on this one). It appears to have not only the basic prayers, but also the Precepts of the Church, cheat sheets for the Liturgy of the Hours, and some other interesting stuff. Of course, if you'd rather have a hard copy of all this, there's always the Manual of Prayers, which is my favorite prayer book, and has all this and more.
