After registration on the Userpanel, you have to open “My Profile” tab. Find “IBAN” and “Variable symbol” (each user has its own variable symbol) and then make a payment in amount of 27 euros (do not forget to specify variable symbol in payment details).
After payment, send payment confirmation to the email email@example.com.
After that, open the “Documents” tab. Download and print the “Application form” document and then sign it and leave it in the box near the reception.
