A WikiProject is a group of contributors who want to work together as a team to improve Wikipedia. These groups often focus on a specific topic area (for example, women's history) or a specific kind of task (for example, checking newly created pages). The English Wikipedia currently has about 2,000 WikiProjects and activity varies.
A WikiProject's pages are not used for writing encyclopedia articles directly, but as resources to help coordinate and organize the group's efforts at creating and improving articles. WikiProjects often write advice for editors, use bots to track what is happening at articles of interest to the group, and create lists of tools and templates their members commonly use. The discussion pages attached to a project page are a convenient forum for those involved in that project to talk about what they are doing, to ask questions, and to receive advice from other people interested in the group's work.
WikiProjects are not rule-making organizations. WikiProjects have no special rights or privileges compared to other editors and may not impose their preferences on articles.

Creating and maintaining a project
Creating a WikiProject is the process of creating a group of people who want to work together.
Before starting, read the guide to WikiProject organization, and peruse some existing WikiProjects to understand how they operate in practice. If you're not sure about creating a new project, or aren't certain if anyone else is interested, you can make a WikiProject proposal. Groups of like-minded editors may start new WikiProjects at any time and are encouraged, but not obligated, to propose them before doing so. Formal proposals have many advantages, including receiving valuable input, and saving a lot of work, and recruiting potential members.
