REGISTRATION
Registrations will be done online through www.easyconferences.org. Participants may pay instantly using their credit card (VISA/MASTERCARD), or by bank transfer. A one-stop-shop software is used for the whole registration process, www.easyconferences.org. The whole process is very easy to use, it is totally secure and can be completed in a few minutes. Please note that participants may not only register for the conference through www.easyconferences.org, but they can also book their accommodation, airport transfers, car hire, etc. All additional services are offered at specially negotiated conference rates.
Please note that the software provides participants with the possibility to complete the registration process in steps/periodically; participants may register for the conference and return later to book further services like accommodation, taxi transfers, etc (subject to availability). The system will accept unlimited changes/updates up to the closing of the online registration process before the start of the conference.
