If you are coordinating an event, but have other people who need to know what is happening (venue, speakers, MC's, partner, business colleagues, family, friends, invitees) and there is a major change to the plan, or even a major milestone that has just been reached, you need to tell everyone what is happening. It is vital to keep everyone informed.

Imagine you are taken sick, or just away from the office when something happens. Can you imagine the panic?

I certainly can, which is why when I am organising an event I always make sure the folders are set up, and everyone knows where to go to find the latest information.

And

A simple email once a week to all interested parties takes away the stress of not knowing what's going on, and your event is less likely to fall prey to gaps in the organization. The "what you may not have thought about" someone else will scenario. That's why events are not just about one person, they are always a team event.
