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)
