We have contacted cryptsy in hopes of getting it listed, no word on that yet.
Due to the nature of mxcnow it is unlikely we will see the addition of much anything there, even doge has taken a long time. That did not dissuade us from trying!
I'll send poloniex another email making a case for the coin, because we love sha3 and we love helix!

Anything the community can do to help is great!

For those that are saying it, we have NOT abandoned this coin!! We like SHA3 too much, and want to support what we think is a good name. We want to see sha3 progress as the healthier alternative for people that have to use rigs, or just like keeping it quiet and cool!
We will not give in. We will not give out. we will not give up!
