License Information YaBB is completely free to use. All we ask is that you keep the copyright in tact and visible on the bottom of your forum. This is to ensure that the project and all of the developers are given credit for their hard work. YaBB is distributed under the YPL (YaBB Public License), which is a slightly modified form of the GPL. You can read this license in the Quick Guide distributed with YaBB. If you would like to remove the copyright, redistribute YaBB, or use it in any other non-standard fashion, please consult the Licenses page. To be allowed to use YaBB, you must keep all copyright notices, both in the script files and all other files, completely intact. You must also keep any license notices provided in the package in tact. Further usage is free, as long as the copyright notices and links to http://www.yabbforum.com remain.

In order to install and setup YaBB, basic FTP and HTML knowledge is required. You need to know how to upload files in ASCII and Binary modes and how to CHMOD them. If you want to edit your forum template (and you probably do), you need HTML knowledge as well. It is also recommended that you have at least basic Perl knowledge to help you change the settings or further customize your YaBB forum to your own specifications.
