I am from Germany, where the Indonesian language is very rarely spoken. It was impossible to find a class for learning Indonesian.
There are some other resources on the Internet, but most of them are focused only on vocabulary.
TIW provides comprehensive materials: grammar explanation, various exercises for reading, hearing and writing but also cultural information about the people in Indonesia.
I also tried “Indonesianpod101”, but it is a bit more expensive than TIW and I like the variety of the exercises in The Indonesian Way, which is why I retuned here.
Since TIW can be used with mobile devices, I can learn at home and while commuting. I am completely satisfied with The Indonesian Way.
