Hi majestyx,
for anyone to become board moderator, he needs to be proposed as a candidate to the Zentyal Community Council (ZCC), which would evaluate the candidacy and take a decision. Candidates need to have shown a commitment in the forum (measured as a minimum of 50 posts) as well as enough technical level and a willingness to help other members.
I believe you are an excellent candidate to become a board moderator and I would be very glad to personally propose the ZCC to make you moderator of the German board as soon as you reach 50 posts (it is pretty easy to reach that number).
Danke!
