FUDforum 2.3 is an Open Source web forum released under the GPL license that is written in PHP 4 and can be used on virtually any operating system. FUDforum combines an extensive feature set while maintaining the ability to generate forum web pages extremely fast.

One of the most significant FUDforum features is the ease of use, which begins right with installation process where a user is guided through 5 step install wizard. The entire installation process even for novice user may literally take less then a minute from the point of installation to the point a user has a working web forum. Unlike installation of similar software, the user does not need to deal with multiple files, all of the forum's data is stored in a single file, the install script. The installation script itself is written in PHP so no additional software is required to complete the installation.

The upgrade process is even easier. After downloading the upgrade script, the user is only required to run the script via their browser, the upgrade script will take care of the rest.
