If you haven't been using Zambobazo, you've been missing out. This web page is full of ideas for practicing your Spanish, music and movie suggestions, puzzles, fun activities, and more. It's geared toward college-age students, and the materials are high quality. They've created a summer e-book with activites. They let you name your own price, but suggest $5. I would suggest paying them something, since their materials are worthwhile and they represent someone's hard work. Check it out!
