as in a signed message that cannot be deciphered until a later date, if I understood correctly what LoyceV did.
I used NeuroticFish's "Option 2": by posting the signature, I could proof the message later on. I used my own bot for it, but you could just post it by yourself if you want.
You're free to use my bot though. I don't know anything about poker, so I won't take part in this.
