I stumbled upon this online flash card website. Languages include Portuguese, Spanish, German, French, Italian, Japanese, Thai, and Russian.

Enjoy!

Nice site find, theres not many sites that do thai but this one does.

Heres some others

Also check out the kool verb conjugation tool. A little funky, missing some verbs and some Spanish verbs in the Portuguese section. But it is better than nothing though.

This one also has electronic flash cards and other methods of learning Spanish.

This one has a whole curriculum including testing and you can actually hear the pronunciations in several different idioms. Spain, Chile, etc.
