No, just need to fill out the part I screenshotted and hit the button. That site is just a helper to trigger the keychain functionality.
About modifying dpoll, I took a brief look but it's fairly difficult as @emrebeyler can also tell you. The tricky part is synchronizing the blockchain comment action and the internal database that is the current source of truth for the tallies. It's on the issue tracker but needs some thought on how to do it properly.
