Turns out being a teacher doesn't necessarily prepare you for being a project manager. So I've decided to use Asana to help me. They have an easy to use interface, and I can share the project with my team of volunteers.
I've decided to use their Board layout and set it up like a Kanban board and organise tasks into "Done" "In Progress" "Ready to start" and "Future Tasks". This way I feel it will be helpful to keep track on what's going on, who is doing what part, and to centralise all my many lists.
You can also email tasks to the board. Which I think will be a good idea, then I can forward my research emails to the board and keep everything in one place.
