By all means, please feel free to use it :) It's created by the multi-talented @fabien so massive credits to him for making it :)

We received an entry fee from an address that had chosen "private" attestation when linking their Steem user from the Byteball wallet. Would it happen to be you? If so - could I get you to do another attestation, this time making sure to choose "public"? It's basically the only way we can tell which users are signing up :-)
