Does anyone know of an online tool for helping small voluntary organisations collaborate on tasks that need doing? I am asking for the hackspace I am in. The idea is for members to be able to post up tasks that need doing with details of what is needed to complete the task, and then for other members to sign up for the ones they feel able to take on and say when they are done. Ideally it should be able to handle repeating tasks, like volunteering to open up at our weekly open meeting. @kdsch
