Flashcards: The world's largest library of printable flash cards

I came across this resource tonight
http://www.flashcardexchange.com/

Interesting for those learners who like to do repetitive learning to help with vocabulary etc. Personally I was looking for Maori te reo resources and this came up in my search to help with my studies.

The claim to have 1,896,622 Flashcards and be the world's largest flashcard library. Some of the format you'd want is only available in the paid membership $16.50 US, one off fee, so I don't suppose that's bad.

Anyone else got any good Maori resources they use?
