MyBB's Merge System allows you to directly convert from several forum softwares and merge into a single MyBB forum. The Merge System allows you to convert only the items you want - such as only users, forums, posts, and threads.
MyBB comes with an English language pack; however, the MyBB Community has also produced a large number of official MyBB translations for visitors who don't speak English. There are even language packs available for right-to-left languages.
Extend MyBB further
There are two ways to push MyBB beyond the default installation: plugins and themes. Plugins extend the default functionality of MyBB, and take just a few clicks to install. Themes give your discussion board a distinctive feel.
