As @antonie mentioned in the Megathread the ZFND stream is to help the Foundation answer questions from the community about the operating structure of the MGRC. It’s not a a ask-the-candidates questions style Q&A, nor is it mandatory.
It’s completely unrelated to Hudson’s stream.
The way ZIP-1014 is written leaves room for clarification about paperwork, contracts, responsibilities, etc… I pointed this out, along with other operational questions in the Megathread, to the ZFND and they decided to host a stream to clarify. If you have specific operational questions about MGRC I would simply join the stream to ask them live.
