Why you OP never do a little of search if there's any Omnicoin before you create such an useless thread. Omnicoin (the name, also the coin) is already taken. You can not use the same name, you must change the name of your coin.
They will probably change the name of the coin. They are using the coin to collect money from users. OmniBazaar might be useful. CryptoBazaar might be helpful. OmniCoin does not add anything to a system where you can use bitcoins instead.
