Hey @lukerhoads , thanks for your contribution! You'll need to sign your commits before I'm able to merge this in. :)

Once you've configured your signing key, you'll need to rebase your branch to only have signed commits (see https://gist.github.com/mattrobertsky/2072b0a1ab81e824a6a5d38240e20b46)

You can probably avoid merging this just now, there are some more issues I am not on PC so cannot sign them right now

Such as the duplicate in questions about the address
