Missing Newsletter: Briefing #4

Hello! I was away from my pc for about a week, and I discovered I missed the Briefing #4: I didn’t receive any mail about it, and my spam folder is empty. Can I get a new mail to download and read it?

Hi, I found it via the official site on reddit.
The news from Gunlord500 4 days ago “The Briefing #4 is out! Sign up to the PP newsletter!”
You can load it in various format

I just got it, thank you!
