Finished Steemit 101. Would like to translate. How to get in touch with the authors?

I just finished Steemit 101 by Hive account@donkeypong, Hive account@cryptoctopus, Hive account@stellabelle, and Hive account@steemship.

It's a great and short introduction to Steemit and very helpful for a newbie like me!

Now I'm wondering: I do a lot of English to German translation as part of my daily work, and I'd like to know if the authors would be interested in a professionally translated version of the book to be put up on amazon as well.

Is there a way to directly get in touch with one of the authors? I'd love to make this available to potential German speaking Steemers
