After you have register and paid your deposit your state of mind should be that you are going to Tangocamp, since almost everyone will be able to join the festival due to the dynamic setup of the event.

However, after you register You will receive an automatic reply from Tangocamp informing you about what information you have entered in the registration. This is not a guarantee that You have made it into the festival. If you for some reason will not make it then Tangocamp will inform you.
Tangocamp also sends out Newsletters. The newsletters are very informative, but not a guarantee that you made it into the festival.
