Hi I.G.S-security,

You can find the details for the developers (keccak512 & nomisugi) on the first page of this thread - they list their BitMessage addresses which is their preferred method of contact.

If you'd like to have a chat about Heavycoin feel free to message me here or contact me on mumbly@mail.com, I can field general questions and in some cases help make sure the devs look out for your messages as we check in with each other about current topics/concerns weekly.

Cheers,
M
