Once you have created a profile on the Lab, you still need to join a project! Anyone can join an "Open" project: simply navigate to the project on the THL projects page, and click "Join." Joining a "Moderated" project requires the approval of a project administrator. Click "Request membership" and you will be added to the project as soon as the administrator approves you. For "Closed" projects, you must be added by a project administrator.
