Have you shown a friend or family member Community, and they want to give it a try for themselves? We actually have a referral program in app to invite people to join. This referral program allows for you to invite your friends to the waiting list to join Community, even if they haven't received the invite to join the waiting list from us.
Simply go to your GoodNotes 5 app > Community > Your Profile > More (...) > Invite Others, and you can follow this pop-up menu to refer them.
Whilst this won't instantly allow them to access Community, this will add them to our waiting list for the beta - so they will be in before you know it!
