                <p>The available slots are marked with the green checkbox.
                If you click on it, it will be assigned to you and if you no longer
                wish to cover that concert, click on the red icon and you will be
                unassigned. A mail should be sent to the admin when this happens,
                but in order for the accreditation request to be sent, you have to
                mail live@eternal-terror.com with the template containing concert
                information. There might be some exceptions, but those are discussed
                case by case. So whenever you want a concert, assign yourself and send
                the template no later than 3 weeks before the concert.</p>

                <p>Admin will try to keep the concert status updated so that you know
                what the accreditation status is. You will get personal message if this
                is really close to the concert date.</p>
