Once your accountn is certified, you will see available projects under Open Projects after you log in:

If no available projects are shown, it's likely because other linguists are currently working on all projects or there is a technical issue (not likely).  Keep checking the Open projects page and your mailbox for a project invitation.

Don't forget to install the Telegram app and enable notifications to get real-time alerts about new projects. Remember, working on projects qualifies you to receive more projects.
