Hey there. My contact information is in my profile, and you can feel free to send me mail about the challenges or just to say "hi".
Two things to know:
(1) We've got ~4800 people involved in these now and we're doing it largely "by hand", so we can't promise not to occasionally screw up.
(2) A small subset of people seem to have email addresses that both our own mail server and our mail client insist are spam sources, and we never see their mails.
If you're having a hard time getting a response from the "official" address, just mail me.
I've received replies within a day or two from them. Depending if you sent yours during one of the bursts from an HN thread it might of got lost. Try sending them an email now?
