Forum Plugins
Plugins are an easy way to install custom codes on a ProBoards forum. A plugin generally consists of Header & Footer codes along with customizable settings. When a developer provides a plugin to a forum staff member, they can download the plugin file (*.pbp files), and import it directly into their forum. When the plugin is enabled, it will automatically insert Header & Footer codes into the correct places on the forum. There is no need for the forum staff to deal with the coding; it has already been handled by the developer.
Plugins can offer very easy ways for forum staff to customize various options without needing to touch the actual HTML / JavaScript / CSS code. Plugin authors are given tools to easily build a custom User Interface where forum staff can input settings for the plugin. These settings are stored in variables that can then be accessed by the Header & Footer codes of the plugin.
