This gallery includes WikiProject member userbox templates sorted alphabetically by project or subproject name. If you are a member of a WikiProject, you may place its member userbox on your user page. Some of these templates have multiple options, so visit the template for further information. A project may have more than one member userbox or no member userbox at all. If the project does not currently have a member userbox, a link to the project is displayed.
