Boljoo, or Boljoo Chat, is a popular freeware Mongolian script instant messaging computer program among Mongols. It is based on a simple Mongolian input-method.
Boljoo IME
There is also a standalone Mongolian input method made by Boljoo, called Boljoo IME. Boljoo IME supports Menksoft and Saiyin codes.
Unlike Menksoft Mongolian IME, Boljoo IME has an English installation interface and is installed as English by default. However, it's a standalone program in the system tray, so you can not find it in ctfmon. And the IME must be enabled before use.
Designed for the Inner Mongolian who cannot speak Chinese, Boljoo IME has a pure Mongolian script installation and using guide.
