A gool vacubary learning tool: Langisle

To learn English is really a tough job, however, a good tool will reduce the pain in a long run.

There are so many tools about learning English, and many of them proclaim that they are using the best technology and of course, it's not free. So today, I am happy to share a tool which not only the software itself is free, but also provide a lot of good learning materials. It's Langisle.
