Registration in DUO category
Due to the requirement of synchronizing results with the WDSF database, DUO registration is possible only in the WDSF database as TEAM. 
Please ask your WDSF National Administrator to create a TEAM (also in the case of DUO) in the WDSF database. 
Only after this operation will it be possible to register in the DUO category. 
For this reason, registration on ECH is possible only in two ways SOLO and TEAM/DUO
