If you were using an Internet translator ... you'd have realized that there is no continuous membership available.
You have to call a specific telephone number (they give it to you after you have selected the country you are in ...) and you will be connected to the site as long as your call lasts ... but be prepared to a big phone bill ... prices per minute vary according to the country of your residence, and are expensive as hell.
Examples: Calling
From Holland ... 0.90 €/minute
From Germany ... 1.99 €/minute
