This is a feature that I think most people would agree on is a verry good feature. It is to bring the event descriptions into Zwift so when you move your mouse over the event the eventdescription would show up.
Here is a picture of how it could look. Just a mockup picture but I think you get the picture of how it would look. There could also be a “Accept/Decline” button at the bottom of the description so that people would have to read and accept the terms of the ride.
