    Registration to the ESO website is requested to:
  • Become a Club ESO member;
  • Register to/apply for an ESO event;
  • Register someone else to an ESO event;
  • Register a group of participants to an ESO event.
IMPORTANT: registration to the ESO website has to be made in the name of the person who is in front of the screen. It will then be possible to register someone else to the selected event, if needed (Third party registration/Group registration). When registering someone other than you, please remember that his/her details are compulsory (you cannot register someone else with your own details). After registration, you will be in copy in all the communications to the participant. For more details, please contact eso@eso.net.
