The first amendment to the NOR is already online. The first part of the amendment refers to the rules that applies, and the second describes the methods of payment. Those delegations that want to pay in advance can do so by wire transference to the bank account which details will be sent upon request. Delegations that prefer to pay cash or with credit card will be able to do so at registration upon arrival.
