Alpha 2 Testing Question - Out of the Loop

Hello All! It's wonderful to see how far Ashes has come in the last few years! I've been out of the loop for a very long while due to some real life circumstances, so I have a few questions about the current Alpha testing if someone would be so kind to help me out. So my account pledge is the "Leader of Men" package from the original summer sale. And I also did some of the really early alpha testing. So do I automatically get access to this round of testing, or is there another path I need to take? How are people getting invited now? Random? Paid? Thank you for your help!
