If I understand correctly, user “Sofirn” is sending the codes out (someone please correct me if I’m wrong). If you haven’t had a BLF PM from them, you might need to send them a PM of your own to point that out.
All codes are being sent by BLF PM, not email. Even if you have your PMs set to notify you by email, the notification doesn’t always get sent.
BLF mysteriously stopped sending me notification emails a couple of weeks ago, even though I could see new PMs when I checked on BLF, and I still had the email notifications turned on.
I turned notifications off, changed to a different email address, then turned notifications back on again - that got it working for me, at least.
My advice: if you’re in the first 500 and haven’t had a PM with your code yet, manually check your BLF PMs from time to time, just in case.
Latest lantern slot I’ve heard of getting a code PM is #397 (ToyKeeper).
