Does anyone know how to submit an solution or even email Mr Sanborn?
I am finding it very odd that even if someone had the solution there is no way of actually verifying it.
I know that there use to be a website kryptosclue but that was shut down over a year ago.
I have also been told that he only accepts emails and a will only reply if a $50 fee is paid but to what email address?
Are we sure part of K4 isn’t his address details as it seems quite a puzzle on it’s own to obtain them.
Thanks in advance for any help.
