Hey Ingo! 
Short answer:
Yes. 
Long answer:
I am aware of the amount of time that contribution to the Board requires. After speaking to other (both current and prospective) Board members, I already came to the conclusion that the “official” requirement of 4hrs/week was probably the low end of the range of estimations, so I’m not running into this under the impression of this being an easy side-gig. Instead, if elected, I fully intend to give this role the amount of effort needed to fulfil my (high) personal standards for a job well done, not just the bare minimum. I am in the lucky situation that mittwald fully supports my involvement in the community and that my role already allows me a very flexible schedule to take time out of as needed; on top of that, I am also willing and prepared to invest additional time from my personal schedule when required.
Regarding attendance at events: We run into each other often enough, so you already know that I’m already a regular attendee of most (if not all) events (both the official events, and community events) due to my DevRel role at mittwald, which I fully intend to keep up.
(Obviously, I will have to learn how to wear two different hats at the same time, but that would be getting a bit out-of-scope for this question, and something that other Board members also do successfully).
Hope that helps!
Cheers,
Martin
