I too am confused by the rules and the lack of support from the official “contact us for support here” email provided.
I signed up with the email account I use most often but then noticed my email needs to be linked to my Unreal account, which uses a different address. I asked them if this is going to be a problem, especially since they said they would contact me via email and the response needs to come from my (forwarding) email address. I got no reply.
So I waited patiently for this event to begin and just now started. I noticed I had already STARTED (but not completed) the first course so I completed it and received no notice of earning my fist badge.
okay, so maybe this Is going to be a problem. So I created a new unreal account using the email address I provided in the first place and completed the first course again. Still no badge.
What the… ???
Is this even really happening or is this some elaborate fake promotion or what is going on?
