English Attack, http://mm.english-attack.com/ is an awesome website. As far as I Learn, they must be very first English language learning online startup. One outstanding thing of them is they are making it fun. They make you learn English language by movies, stories and games. They are running by freemium type of business. They will let you use free. Later you will have to pay if you want to use advance features, which may have you more resources to learn. That startup is running by foreign people in Myanmar. They will monetize by selling learning content.
There are not too much websites in Myanmar to learn. We usually had to surf websites from other countries which are not much relevant to us. Now we have a website which focus for people in Myanmar and Myanmar people from other countries. Check them out!
