Crabgrass is a software libre web application designed for social networking, group collaboration and network organizing. Our goal is to create communication tools that are tailored specifically to meet the needs of bottom up grassroots organizing. By social networking, we mean the ability of users to get to know one another through their online contributions and presence. By group collaboration, we mean the ability of small groups to get things done, such as share files, track tasks and projects, make decisions and build repositories of shared knowledge. By network organizing, we mean the ability of multiple groups to work together on projects in a democratic manner.
