The challenges from HES2013 and NSC2013 are still available.
Brought to you by Steven!
All who had an account on (?:nsc|hes)2013.wechall.net have to check out their new username.
It is either the old name, or prefixed by "NSC_"
You can figure out your new username by studying the NSC scoreboard
All old NSC/HES Users have to go to the PasswordForgot procedure, because i used a different pepper for the password hashes.
If you want to merge your NSC_ account, simply resolve, if it´s too much trouble, i will code something up.
I am sorry for the inconvinience, and wish you
