CommonSource accounts are set up by the CommonSource team. You can't sign up on your own.
You get access in one of three ways:
The CommonSource team creates your workspace and invites you as its account owner.
A colleague invites you to a workspace they own.
You claim a page that the CommonSource team prepared for your organisation. See Claiming your organisation's page.
If you'd like a workspace for your organisation, message us using the chat in the bottom corner of the screen.
