But I don't have any priv/pub key (that was the procedure 2).
See point 3:
We will perform the keygen procedure for you and send you bitcointalk.org PM confirming your investment and giving you your Heavycoin Address. We will hold the private key on cold storage for you.
IPO details van still be found here:
http://heavycoinforum.com/index.php/topic,2.0.htmlI see. So I should receive a PM before March 6th so I can check everything.
