This challenge is really great. I'm stuck on task 6 because I'm somewhat lacking time and motivation, but I'd definitely recommend it to anyone interested.

How long did it take for the server to reply against Task 5? Its been a week since I submitted my results but no reply as of yet.

For me it took 11 days.

The upside to the delay is that it seems incorrect submissions get returned a lot sooner than correct, so you're likely on the right track :)

Am I too stupid to even get an invite or is it taking so long to process? I tried multiple times, even analysing whether the email is in text and not html format..

Never saw it.

I've been waiting about a month for confirmation that Task 8 is correct (or incorrect, either way!). Anyone else had issues with this one?
