I just realised something (like 2 months after the fact).
I've provided an Ethereum address during my signup to the signature campain and I used this same Ethereum address to join the ICO.
But AMON is not an ERC20 token, right? Where am I going to receive my signature tokens, on the account created from the ICO or is this an ERC20 token after all and I'll receive the reward in my Ethereum address?
AMON Tokens are part of ethereum chain and you would receive the bounty tokens on the address you provided during signup for the campaign. Just have a check if the address is the same used earlier.
