By my experience, Cryptsy is the hardest exchange to get listed on.

We didn't contact them, I don't remember if old developers did. Anyone is free to contact them if you think we can get listed on cryptsy. We will not contact them yet, it would be a good idea for MACDCoin to be listed on smaller exchanges first and then try with Cryptsy.

MACDCoin is next in the line for listing on cryptoine.com and it will probably be listed on askcoin.net relatively soon (in a month or so).
Also, now that we have a working explorer we will try and get it listed on allcoin.com.

If we manage to have MACDCoin on those three exchanges in next several weeks, I think that is a good start.
