I had all the same thoughts and questions. I just had my sister sign on the witness line, and did an E signature through noteability. I don't know if that was okay, but they didn't give much instruction and I don't have access to printer. I'm guessing whatever we do as long as it is uploaded we should be okay.I got the email with the NDA today. I see that there’s a spot for a witness to sign. Did you guys just have a friend or family member sign there? Also, did you use an E signature or did you print, sign, and scan?
