Hello kihrEx,
thank you for contacting us with your issue.
I am sorry that you can not access this thread at the moment.
It was blocked in the meantime to process all the invites, but it may reopen soon.
You should be allowed to post in this thread, as soon as it opens again, because you have the beta tester tag.
This was a response by WG Support to my ticket about the CBT Referral program. So apparently it is closed right now, but should open at some point soon I guess.
And yes, weekend beta testers should have the chance to get into this referral thingy.
