I would like to register in a prediction community but my invitation code is not being accepted.
Please note that we send you an activation code when you register to validate your e-mail address. This is not the Invitation code. Both codes are often misunderstood and swapped.
The invitation code is sent by the administrator or another player. We at Kicktipp cannot send you an invitation code.
By the way: Not every prediction community needs an invitation code. Most of them are actually open to be used.
