First obvious question from someone highly interested in finding and rewarding high quality content creators: Is there an API to retrieve a user's UA ? I'll ask @Fabien directly to see if it's possible to have it built into SteemConnect (that the Byteball rewards rely on) for an even easier access.

Congratulations on the massive progress. Guess it must be incredibly satisfying to take a look back and see how far you've managed to get in such short amount of time. Props to both you and @Holger80.
