Does anyone know the link to where to get the wallet as I was going with:
https://dnotescoin.com/Unless there's a difference between Dnote and Dnotes (i assumed they were the same).
That's the right site, so i think that there might be some problem on poloniex's (or OP's side).
Im not that familiar with the coin at all, so maybe grab some address from cryptopia for example and withdraw from there to your own wallet or something, or try generating a new address?
