The ability to create private races similar to meetups but with the ability to setup events from starting pens and include elastic band effect and fencing.
Would also love the ability to be able to grow the community by inviting non zwift friends/family and colleagues to the private race via social media links.
The trial accounts could join these type of events arranged by a current zwift account holder for a limited period say 7 days so that they can get a taste for the many friendly group rides out there with people they already know.
