A collection is a list of trees, chosen for synthesis or any other purpose. Each collection has a nominal owner, but any logged-in user can choose to collaborate (add and manage trees) or simply follow its progress.
Collections are stored as documents in GitHub, a collaborative coding website. This curation tool makes it easy to edit and contribute data, but you'll need a (free) GitHub account to participate. Once you've created an account on GitHub, just login using the link above. Once you've agreed to give access to the OpenTree tool, you can start adding collections immediately.
