Participation and presentation certificates

Participation and Presentation certificates are available on your Home Page at for all participants who are up to date with their registration fee payments.

There are payments by bank transfer which do not show any information and therefore could not be attributed to anyone. If you are in this situation, please send us a copy of the receipt or the date of the transaction.

Participants who have paid by credit card and have received an OK page and are found to be in default should check their credit card account. They will see that the amount has not been charged because the transaction was not accepted for various reasons. They can try again with another card or make a bank transfer following the instructions available at

If you have a credit card payment on your account, please inform us.
