I did not use it, but visited one event and paid extra for it, and payed additionally more than 100 EURO for some kin of subscription! they are shameless and not friendly, poorly organising events. I noticed that they subscribed me just on the second year and the same day I have canceled, but they charged for the next months and send me several mail highlighting that it is ok that they do not warn getting your money, but just take it. do not use the service !!
