For everyone with a poloniex account:
AEON has been listed on poloniex before and according to smooth their wallet has been updated. So I would like to ask everyone that has an account to send them a message that you would be interested in trading AEON (again). You can just open a support ticket and I think the mods will pass it along. Personally I hope it gets reenabled, more exchanges means more awareness.
If you check the options on polo there is an option for suggesting a coin. I have submitted the suggestion and the reasoning. With Monero so popular there, and the great dev here, Aeon is an obvious choice now. (with future potential based on new development)
I've been bugging them via trollbox. Eventually they will cave.
