I tried to sign-up to this today, as the event looks great.
Sadly, when loading their privacy policy, a huge un-dismissible pop-up appeared on the screen. I've tabbed through the page twice, and there's no way to focus on the pop-up to close it.

(No, it wasn't a GDPR compliant notice, it was advertising the event that I already want to sign-up to... but now can't because I'm stuck on the pop-up)
