I've been studying the reference, and other documents, and if I am not mistaken, we need either the messages or the public key to set up the equations. True?

I'm afraid I didn't get any notification either. I checked the emails that my email provider filters out as spam. Nothing.

I've gotten used to it a bit. It's the reason why I poll every 30 minutes for a new challenge. Just in case anyone is wondering.

Hey everyone,

there are issues with our email system which we just discovered and now resolved.

Unfortunately that is also the reason why you didn't get the notification and neither did I get the notification for the replies in this topic - sorry!

Then is it impossible, since neither is available?
