Found another great Russian course to supplement DuoLingo!
Greetings, comrades. First of all, a HUGE thanks to the contributors for putting together Russian on DuoLingo! If you're looking for a more comprehensive course to supplement free resources like DuoLingo, I would definitely suggest "Daily Russian: An Innovative Russian Course" from Amazon. Someone posted about it on here a couple weeks so I checked it out; and I have to say, it's definitely my favorite course. It's also a joy to study with - very user friendly. Anyway, hope someone finds this as useful as I did!
