There is no Blackcoin thread, I've just checked all the threads on https://bitcointalk.org/index.php?board=142.0and the entire altcoin section (https://bitcointalk.org/index.php?board=164.0). Also, from this "ancient" post https://bitcointalk.org/index.php?topic=469640.msg5428187#msg5428187 it seems that the bounty is still availible, so I think I can start. Just tell me if this would be a good section: https://bitcointalk.org/index.php?board=164.0
