First of all, please stop spamming your link across multiple threads.
Second of all, I had a look at the site and don't really quite understand the point. It just looks like multiple lists of random Japanese vocabulary words with English definitions. There doesn't seem to be any structure/theme, example sentences, or anything other than endless vocabulary lists presented without any context, guidance, or explanation.
How is this "course" supposed to be any different or more useful/helpful than just using a good textbook or reference materials together with a dictionary to look up words you don't know?
