Ah! Okay. I mean, I saw it a few days late, I had to alter some things in my email account as it was sending all of my message notifications to my spam box, but keeping the eden newsletter in there? Ah well.
I was accepted as a new DR reviewer, and was given an assignment. I had responded to the message a few hours after it went out, and was notified that I was accepted shortly adterwards, possibly the following day if I remember correctly.
