Hey all - I've found a great website for language learners. It's called LingNet, and, being run by the military, is a little...ok, very heavy on the jargon and abbreviations , but at least the Russian material that I've looked through so far is really good quality. There are two main resources - GLOSS(DLI-LangNet) and Online Language Courses. GLOSS has audio, video, and text for all levels in Persian, Arabic, Chinese, Spanish, and Russian. The Online Language Courses section has basic material for Arabic, Chinese-Mandarin, and Korean. There are also materials for Persian, Russian, and Serbian/Croatian posted there - I'm not sure who they're targeted for, though. The materials that I've seen so far in GLOSS are in a very nice lesson format - once you find them. The search feature is fairly cumbersome.
I could go on and on, but I think I'll just stop here and leave you all to explore it for yourselves. Hope it's useful for you.
