Would you like to try out Weaver?
You do so by creating a “Site”. A site is a space where you can set up a number of workspaces without disturbing anyone else. This acts as the containing folder for your entire organization.
Inside of a site you create workspaces. A workspace allows groups of people to work, to share documents, ideas, notes, and plans and to keep this separate from the other working groups. You will be able to create as many workspaces as you want. Each workspace has its own list of people who can access it.
