I think this is rather amusing.
If you go to the AI-class FAQ the first thing you will see is:
Q: What if I don’t receive a verification e-mail after submitting my enrolment?
A: Confirm that it is not in your spam box.
Which is funny, isn’t it? I mean, it’s applied AI that is doing your spam filtering, and the most likely cause of you not getting your email from the AI-class is that the AI that’s filtering your mail is wrong with a false-positive.
Well I think it’s funny. :P
