Tournament organizers can now assign other users as staff to their tournaments. Tournament staff members have the same access level as the tourmanet organizer, and can help manage the tournament by registering players, entering results, or any other organizer task. This should allow larger tournaments to give the full organizer crew access to managing the tournament, without the need to share a single account between them.
Tournament staff is managed from the "Edit Staff" page, which you can find a link to on the "Edit Tournament" page, under the "More Actions" section.
