Payment should now be made through PayPal (below). There is an additional charge of €1 to cover the cost of the transaction.
The current year of payment is 2017. If you neglected to pay your dues in 2016, you may do so by selecting the option: Dues for 2016 and 2017.
You do not need to create your own PayPal account to pay your dues. When you arrive on the PayPal page (after you click on the button 'Buy Now'), you may select the option 'Pay with Debit or Credit Card'.
