If you don't have a SciNote account:
When a person invites you to their team, and you do not have a SciNote account yet, you receive an email with a confirmation link to join their team. The invitation is valid for 7 days. After you confirm the invitation, simply log into your SciNote account and use the Global team switch button at the top bar of the home screen to see the team to which you have been invited and access the projects.
If you already have a SciNote account:
If a colleague invited you to join their team, you will receive a notification email. Make sure your Assignment notifications are turned on under your account settings in the Preferences tab.
Otherwise, you will only see the notification under the bell icon at the top bar of the dashboard.
