Just throwing this one on the pile.
As a Zwifter when I am invited to a meetup, I can forward it to a friend on my list.
Value statement: Your friend can meet your friend(s), and perhaps they will become friends too (let them decide).
Additionally, you may need to increase the meetup limitation of 50 invites to 100.
AC1: An invited zwifter can forward the invitation to another zwifter on their own friend’s list.
AC2: The meetup should be larger than 50 people when allowing this.
