The Email challenge (#21) appears to be broken again. No mail is being received. Tried with multiple mail services to no avail.

12 May - 11:47 am

Working again now.

10 May - 4:05 pm

Hello, sorry for the late answer, in fact yes there is an issue with the mail, we will try to fix it quickly. Thanks for reporting

7 May - 6:07 pm

Hi there is a issue for the challenfe Email (number 21). I don't receive a mail on any of them: gmail, hotmail, yahoo. do i fail or is it the challenge ?

28 Feb - 10:35 am

Yes we fixed it

27 Feb - 10:00 pm

Thank you, just validated contest22. The solution checker seems to have been fixed.

27 Feb - 8:40 am

Yes several solutions are accepted of course. I will check one of your answers

26 Feb - 7:51 pm

No 500 error, but the solutions I'm submitting can be verified to be correct. It can't be that only one configuration is accepted, right? - as there are multiple correct configurations for each problem.

26 Feb - 5:54 pm

contest 22 is not concerned by the issue I found, and seems to be working (I suppose you don't have 500 error on this one ?). Your solutions are indeed rejected, but I did not check them yet

26 Feb - 3:25 pm

The validation for contest 22 also seems to be wrong (it's not accepting solutions that are clearly correct). I submitted bug report yesterday.
