Let 2000 people to sign up for a 300-person event, and didn't tell anyone!
Went to their "Power of Momentum" training after Tony Robbins' Birmingham event. Many people had to reschedule flights & take an extra day off to attend this because it wasn't announced together with Robbins's event. Then, on the morning of the event, everyone gets an email saying that 2000 people signed up for 300 spots so "arrive early" - I guess 1700 people signed up overnight so they couldn't have predicted this! A huge pile of people were sent off to attend a poorly-implemented zoom call (where the camera didn't show the slides). To top it all off, the hosts of the zoom meeting ignored many questions in the chat.
