In recent years as the web has become more dynamic Internet Diplomacy has shifted from email to the web.
Due to the complexity of adjudicators and judges, the earliest web implementations primarily provided a web interface to the email based Judges.
One of the main advantages of web-based implementations over previous options is that they can display computer-generated graphical maps of the current board on the web-page, instead of requiring the user to update the positions of the game's units on a physical board based on text output.
In 1995, Manus Hand created the DPjudge, among the first to use a web interface for an email judge.
Those adjudicators often had many bugs and only after a few years they became reliable.
