The page and method of subscribing has slightly changed (to subscribe click on participate and then on the page enroll for 20h or 21h)  You will see a counter running towards zero.  When zero is struck you will be able to fill in RegistrationID and confirm (page will change at that particular moment).  Refreshing of the page with F5 is no longer necessary.

When you can, fill in your registrationID and confirm, you will be added to a queue and your request will be processed.  The wait time can be up to 30 seconds before notice will be given by the server depending upon serverload. (you will see the status on screen)

A confirmation mail with payment details will be send when all subscriptions have ended.

Please check your Spambox since sometimes our mails tend to be posted there.

Good luck!
