JDim (JD improved) offers a comfortable browsing experience on 2ch-style bulletin board systems. Its features include:

- automated login, - message viewing/posting, - image viewing, - mouse gestures, - ignore lists, - "play-by-play" mode.

It can also significantly reduce the load on servers by bypassing CGI programs and directly retrieving thread data files to your local hard drives.

"2ch-style" web forum sites have their origins in 2channel, which was a very popular Internet forum in Japan. Such sites are often available only in the Japanese language.
