I have started to learn Indonesian with the help of some great online resources. I scrapped the idea of taking classes after I found them. But self learning is sometimes more time consuming as you don't have deadlines and exams. So I haven't had much progress. But hope I will be able to speak decent Bahasa in three months time.
Here are the online resources for learning Indonesian.
