When someone invites you, you get an email with a link to join their workspace.
Open the link in the email.
If you're new to CommonSource, choose a password of at least 8 characters and confirm it.
Select Accept invitation, then Go to my workspace.
If you already have a CommonSource login, sign in with it and accept the invitation. The new workspace is added to your account.
To sign in later, go to the CommonSource sign-in page and enter your email and password.
If the link says it's invalid or has expired, ask the person who invited you to send a new invitation.
